Director: Dr. Andrew J. Roger Coordinator: Wanda Danilchuk (494-3569) Phone: 494-2620 Fax: 494-1355 Website: http://www.cgeb.dal.ca

The vast majority of biodiversity on Earth is microscopic and unicellular. These organisms play key roles in all known ecosystems and have done so since life first arose on the planet ~3.8 billion years ago. Microbes are the major primary producers in the ocean, they produce most of the oxygen we breathe, they are central players in nutrient cycling in terrestrial and aquatic habitats and are abundant commensals, symbionts and pathogens capable of causing disease in humans and other organisms. Yet despite their importance, until recently, very little was known about the ‘true’ diversity of unicellular organisms and their environmental impact beyond the few that were culturable in the laboratory. Research on microbial diversity and genomics in the last decade has revolutionized our understanding of the microbial world. It is now possible to isolate diverse unicellular organisms from the environment and characterize their genomes quickly and cheaply. Furthermore, meta-genomic technologies allow genomic surveys of whole microbial communities without the need for culturing at all. With the resulting exponential growth of genomic sequence databases and associated meta-data, development of computational and statistical methods for extraction of biologically meaningful information and hypothesis testing is becoming increasingly important. It is at this nexus of genomic, computational biological and evolutionary research that the internationally recognized researchers at the Centre for Comparative Genomics and Evolutionary Bioinformatics (CGEB) at Dalhousie University are making important advances.

CGEB encompasses ten researchers in the Faculty of Medicine [Andrew Roger, Ford Doolittle, Michael Gray, John Archibald, Claudio Slamovits], Faculty of Science [Joseph Bielawski, Alastair Simpson, Ed Susko] and Faculty of Computer Science [Robert Beiko, Christian Blouin]. The main focus of the Centre’s research is understanding how microbial genomes evolve and diversify, however the research programs collectively span computational biology, computer science, statistical modeling and comparative genomics, with a strong focus on method and theory.

The Centre was officially approved by the Dalhousie Senate in June, 2008 with the mission to foster collaborations amongst a ‘group’ of nine comparative genomics/bioinformatics and microbial evolution researchers at Dalhousie. Specifically, the CGEB Centre’s goals are to: 1) recruit new world-class comparative genomics/bioinformatics researchers to Dalhousie, 2) recruit top-notch postdoctoral fellows and Ph.D. students to CGEB labs through the provision of Tula Foundation stipends and research allowances, 3) create a CGEB seminar series to attract world- class speakers to interact with CGEB principal investigators and trainees, 4) fund CGEB trainees to attend and present their work at national and international scientific meetings, and, 5) provide a framework that promotes collaborations between CGEB members and attract external research funding. Over the last year and a half we have

1 met or exceeded all of these goals. This Annual Report records the achievements of the Centre to date, the highlights of which are summarized below.

CGEB research productivity, funding and collaborations. During the period of 2008-2009 inclusive, CGEB researcher have published a total of 99 manuscripts in peer-reviewed journals (pp. 9-15), including contributions in high impact journals such as Science, Proceedings of the National Academy of Sciences USA, Trends in Ecology and Evolution and Current Biology. The fact that 55 of these publications are from 2009 (as of Oct. 1st) underscores the tremendous positive impact CGEB has made on our collective research output in the last year. The international profile of CGEB researchers is further demonstrated by the 57 invited presentations given at international conferences or invited seminars from 2008 to 2009 (32 in 2009 and 25 in 2008). Furthermore, in the last two years CGEB members have been awarded a number of prestigious Honours and Distinctions (see p. 27). The CGEB trainees (postdocs, graduate students and undergraduates) have also been productive beyond their contribution to publications. They have presented their results at international meetings (a total of 44 seminars or posters presented in 2008-2009), and, in the process, gained invaluable presentation and networking skills. The CGEB Trainee Travel/Meetings funds provided by the Tula Foundation have been of great benefit in supporting the latter activities.

A large portion of CGEB research efforts is directed at development of computer software tools for evolutionary modeling analyses and bioinformatics. In the last year and a half, 15 ‘open-source’ software tools (or suites of tools) for analysis of genomic data have been created, published and made available to the international scientific community through free web access (see pp. 16-18).

CGEB researchers have also been extremely successful in attracting external funding, garnering a total of ~$2,930,600 of external grant support in total over 2008 and 2009 from Natural Sciences and Engineering Research Council of Canada, Canadian Institutes for Health Research, Canada Foundation for Innovation, the Canadian Institute for Advanced Research, as well as the Tula Foundation.

Finally, CGEB has greatly facilitated collaborative interactions between the member researchers leading to joint publications, software development and grant applications (see p. 23). The CGEB journal club, joint lab meetings, seminar series and, in future, the annual mixer/poster session will continue to foster CGEB collaborations and synergy.

CGEB faculty recruitment. With the financial help from the Tula Foundation and the Canadian Institute for Advanced Research (CIFAR) Program in Microbial Biodiversity, we created a new CGEB position within the Department of Biochemistry and Molecular Biology. After an international job search we hired Dr. Claudio Slamovits to join the Department and CGEB as an Assistant Professor as of July 2009. The comparative genomics themes of Dr. Slamovits’ research program fits well with activities of the CGEB community.

2 CGEB postdoc and student recruitment and training. Since we first received the trainee funds from the Tula Foundation we have recruited seven top-notch postdoctoral fellows and two Ph.D. students to fill these positions. The importance of these Tula-sponsored trainees to the success of our research programs cannot be over-stated. As these individuals are often already accomplished young scientists, they bring new techniques/knowledge to CGEB labs, as well as help train the younger, less experienced students in the labs (thereby gain invaluable supervisory experience). This is especially important to the success of the CGEB labs because the number of trainees collectively has increased to a total of 67 (see pp. 28-30).

Although we have been successful in recruiting the ‘first wave’ of trainees to CGEB labs, some aspects of the current policies and procedures relating to postdoctoral training at Dalhousie poses a significant risk to the future abilities of CGEB researchers to recruit top-notch postdocs. Specifically, the lack of a postdoctoral trainees benefits package and current three-year restriction of the ‘academic postdoc’ designation (that enables these individuals to claim their stipend as non-taxable fellowship income) will make it difficult for us to compete with other institutions to attract top-notch candidates. We have twice pointed out the flaws of the current system to the Faculty of Graduate Studies in charge of postdoctoral training (see attached letters in Appendix B), and we hope that changes in the policies will be made to address these issues.

CGEB seminar series. The CGEB Seminar Series is in full swing and has hosted seven well-attended seminars from internationally recognized researchers (see p. 36) with two more scheduled to occur in the next few months. The Seminar Series has expanded to include sponsorship of symposia in meetings held at Dalhousie University by paying for the travel and accommodation of the guest speakers. In return, CGEB members are free to choose the topic of the symposium and the speakers that will present. So far we have sponsored three such symposia (see pp. 36-37), two of which occurred in the context of national or international society meetings (International Society for Evolutionary Protistology/Society of Protozoologists and the Canadian Society for Ecology and Evolution).

New CGEB activities and future directions. So far, group CGEB activities have consisted of a journal club, monthly group lab meetings where CGEB PIs or trainees describe their ongoing research and the CGEB seminar series. Owing to the increasing size of the CGEB group, we are planning to host an annual CGEB poster night mixer to promote intra-CGEB networking and collaboration. If we can procure sufficient additional funding, this event could grow into an annual retreat meeting with invited external speakers. Another future activity may be to co- or fully sponsor workshops in comparative genomics and phylogenomics methodologies; the purpose of this would be to promote the acquisition of new skills and again allow CGEB researchers to interact with other internationally renowned scientists. These and other future directions are being actively discussed amongst the CGEB membership (see pp. 38-39).

4 III. FINANCIAL STATUS OF THE CENTRE

The Centre’s administration (i.e. 50% administrator’s salary, seminar series fund, and student travel funds) is supported by funding from the Tula Foundation at $50,000/year for 8 years, 2007-2015 (see Table A. below). The other 50% of the administrator’s salary is covered by contributions from the Faculties of Medicine, Science and Computer Science, and the office of VP, Academic & Provost. Five-year financial commitments from Dalhousie were established and annual installments for years 1 and 2 have been received (see Table B. below).

A. Tula Foundation Contributions

Fiscal Year 50% salary of Seminar Series Trainee Travel/ (August 1-July 30) administrator Fund Meetings Fund TOTAL Year 1: 2007-2008 $25,000 $15,000 $10,000 $50,000 Year 2: 2008-2009 $25,000 $15,000 $10,000 $50,000 Year 3: 2009-2010 $25,000 $15,000 $10,000 $50,000 Year 4: 2010-2011 $25,000 $15,000 $10,000 $50,000 Year 5: 2011-2012 $25,000 $15,000 $10,000 $50,000 Year 6: 2012-2013 $25,000 $15,000 $10,000 $50,000 Year 7: 2013-2014 $25,000 $15,000 $10,000 $50,000 Year 8: 2014-2015 $25,000 $15,000 $10,000 $50,000 Total: $400,000

The Seminar Series Fund enables us to invite world-renowned scientists to present seminars at Dalhousie University. The Travel to Meetings Fund enables our CGEB trainees to attend scientific meetings and workshops.

The Centre is also supported by individual research grants from the Tula Foundation to each CGEB faculty member for postdoc trainees ($44,000/year) or graduate student trainees ($25,000/year). In addition, these grants provide a research allowance for each trainees’ lab ($20,000/year for molecular biology PDFs, $5,000/year for computational PDFs, $2,500/year for computational PhDs). These grants are awarded for five years.

In summary, the Tula Foundation has invested over $3,000,000 in the CGEB centre.

5 C. CGEB New Opportunities Fund

Another source of funds available to finance CGEB activities is our New Opportunities Fund. This is a “special purpose account” (# 6-8292) that was opened to receive transfers of revenue that was generated from CGEB faculty activities. The purpose of this fund is to provide additional partial funding or ‘seed’ monies for CGEB activities, the costs of which either exceed existing allocated funds (e.g. the Trainee Travel/Meeting fund, the Seminar Series fund) or one-time events/activities/opportunities that fall under the CGEB mandate. For example, in 2008, the New Opportunities Fund sponsored student travel awards at the international ISEP meeting held at Dalhousie campus that had major CGEB faculty and trainee involvement. Furthermore, through this fund CGEB co-sponsored the Mitochondria, Ribosomes & Cells meeting at Dalhousie in 2008 with the Canadian Institute for Advanced Research (CIFAR) (see pp. 36-37 for details under “CGEB Meeting Sponsorships”). To date these funds have also been used for costs associated with recruitment of potential trainees to CGEB labs (e.g. interview travel and accommodation costs), as well as CGEB website design and maintenance (see http://www.cgeb.dal.ca).

The first source of revenue for this fund came from the Society for Molecular Biology and Evolution Conference which resulted in a net income of $39,181.46. Second, Drs. Doolittle & Gray had been maintaining an account from a conference in 1981 that had generated a net revenue of $10,073.15. In 2008 they generously donated these funds to the CGEB New Opportunities Fund. Finally, another symposium (“Mitochondria, Ribosomes & Cells” in 2008) generated net revenue of $106.01.

The current balance is $40,123.29.

6 IV. CGEB GOVERNANCE

CGEB Governance structure and policies (see Appendix A) have been working smoothly since the creation of the Centre. As the Centre has only ten current members and maintains no core Centre-specific research facilities or equipment, governance is not onerous and no problems with our procedures have surfaced.

According to our governance guidelines, the CGEB Director is to meet annually with the ‘Deans Committee’ for discussion regarding Centre operations and directions. Although official approval for CGEB was given in June 2008, we did not convene a ‘Deans Committee’ meeting in June 2009 because both the Faculty of Medicine and Faculty of Science were in a transition period moving to the leadership of new Deans. We thought that the best course of action was to wait until Dr. Tom Marrie (Dean of Medicine) and Dr. Chris Moore (Dean of Science) had assumed their positions this summer and to arrange for a meeting in the Fall. The Deans committee meeting will be arranged for late October or November, 2009.

Since the official designation of CGEB as a University centre, we have had two ‘biannual’ CGEB members meetings attended by all PIs. In these meetings we have constructed additional policies and procedures relating to Centre activities, trainee recruitment, disbursement of Tula-sponsored postdoc and PhD fellowships. These are briefly summarized below:

A. Recruitment and vetting of potential Tula-sponsored Trainees. Once a CGEB member has found a suitable candidate to fill the Tula-sponsored postdoc or Ph.D. student position, he/she will send the CV of the candidate to the Director and Steering committee who will adjudicate the application. If they find that the candidate is acceptable as a Tula-sponsored trainee, the member is informed and the CGEB Administrator (Wanda Danilchuk) liaises with Research Services, Financial Services and the Tula Foundation to set up the appropriate accounts in anticipation of the trainee’s start date.

B. Disbursement of Trainee Travel/Meeting Funds. The $10,000 annual budget for CGEB trainee travel/attendance at meetings is divided equally amongst CGEB labs. If any monies are left over from the previous year, then these monies get rolled into the next year and added to new $10,000 allotment. The total is then divided by ten (total number of CGEB labs) which becomes that years ‘allocation’ for each lab.

C. Seminar Series. All CGEB members are invited to suggest (to the Director) potential seminar series speakers covering their areas of interest. If the Director approves the choice, the speakers are invited by the CGEB member who will serve as host for the speaker’s visit. While the speaker is at Dalhousie, CGEB members (and their trainees) are invited to meet with the speaker and/or have lunch/dinner with them in order to promote interaction and discussion. An honorarium of $500 is given to each seminar speaker. Where possible, CGEB will partner with a member’s home department to co-sponsor high-profile speakers.

7 The membership has decided to extend the Seminar series fund to cover sponsorship (or co-sponsorship) of dedicated symposia at meetings held at Dalhousie in the area of interest of several of the CGEB membership. These symposia can be part of larger international meetings held in Halifax. However, if CGEB sponsors or co-sponsors a symposium, all CGEB members and trainees may attend without paying meeting fees (although usually many of them are already registered to attend the meeting). CGEB members are free to make proposals of CGEB sponsorship of these symposia at any time and the Director decides on the eligibility in consultation with the membership and steering committee. The CGEB seminar speakers invited, and symposia sponsored, to date are listed on pp. 36-37.

D. The ‘CGEB Associate’ position. At the last CGEB members meeting the possibility of adding a new category of CGEB affiliation was discussed. A proposal for a ‘CGEB Associate’ category was voted on and unanimously supported. CGEB Associates were defined as faculty members at Dalhousie University whose research is aligned closely with CGEB goals and who may be active collaborators of CGEB members, in some cases co-supervising trainees. The CGEB Associate status does not entitle the faculty member to any financial contributions from the Centre, nor entitle them to Tula-sponsored trainee positions. However, Associates and their trainees will be invited to all Centre activities (i.e. sponsored talks, symposia, workshops etc), can suggest seminar speakers and will be able to participate in co-supervision of Tula-sponsored trainees with a CGEB member to whom the trainee monies are awarded. We hope this category makes it possible to expand the impact and interactions of the Centre without diluting its financial resources. To become a CGEB Associate, a CGEB member will ‘sponsor’ the candidate and circulate their CV to the membership and provide a brief justification as to why the individual deserves Associate status. The Director will decide on the appointment in consultation with the membership and the Steering Committee.

22 VIII. COLLABORATIVE INTERACTIONS BETWEEN CGEB MEMBERS

In the last two years, collaborative interactions amongst CGEB labs have flourished. Evidence of this can be seen in the 16 publications in 2008-2009 (pp. 9-15) that were co-authored by two or more CGEB members and their trainees. Below a short summary is provided of the collaborations that are ongoing within CGEB:

Archibald and Gray are working on the analysis and annotation of cryptophyte nuclear and organellar genome data coming from the Joint Genome Institute. They are co-PIs on an NSERC Strategic Opportunities Grant to sponsor this work and co-supervise Tula-sponsored postdoc Dr. Goro Tanifuji (allocated to Gray).

Blouin and Beiko have been involved in the development of methods (e.g. the software tool GenGIS) that integrate geospatial data with genomic (and metagenomic) data.

Beiko and Archibald are developing phylogenomic methods for analysing eukaryote and prokaryote genomic data to be integrated into the MOA database. They co-supervise M.Sc. student Rob Eveleigh.

Roger and Gray are working together to elucidate the origin and function of enzymes of anaerobic energy metabolism in the aerobic amoeba Acanthamoeba castellanii.

Susko, Roger, and Blouin have worked on the development of methods for curating protein alignments (e.g. the development of the software tool MANUEL) and site- independent models of protein evolution that take into account structural information.

Susko and Roger have been developing tools for phylogenomic analysis (e.g. CONCATERPILLAR), sophisticated models of protein evolution (e.g. QmmRAxML and PROCOV-SPR), methods for assessing the quality of EST data and theoretical contributions to the understanding of molecular evolution. They co-supervise Tula- sponsored postdoc Dr. Huaichun Wang (allocated to Susko).

Roger and Beiko began a collaboration this summer to determine whether an ancient vertical phylogenetic signal exists for core proteins in the domain Bacteria or if it has been completely erased as some have claimed.

Roger and Simpson are collaborating on understanding the phylogeny and evolution of the most enigmatic eukaryote supergroup – the Excavata by EST surveys and phylogenomic analysis. They co-supervise Ph.D. student Martin Kolisko.

Doolittle, Bielawski and Beiko teamed up to write a CIHR grant application entitled “Beyond species: modeling and mapping microbial diversity and function with marker genes, genomes and metagenomes” that was submitted in the Sept. 2009 operating grants competition.

Susko and Doolittle have collaborated over the last few years in developing methods with Eric Bapteste (former PDF) to probe the extent of lateral gene transfer in prokaryotic genome evolution.

C. CGEB Joint Lab Meetings

In 2009 we instituted a new schedule of CGEB joint lab meetings that include all ten CGEB labs’ faculty members, undergraduate and graduate students, postdocs, and lab personnel. These meetings are held on the first Thursday of every month, to be continued on a year-round basis.

The purpose of these meetings is to introduce CGEB faculty and trainees to the ever-expanding group of trainees in the various labs. Faculty members and/or their students and postdocs provide an overview of their research program in a seminar-style format, with adequate time allotted for questions, constructive criticism and open discussion throughout.

D. CGEB Journal Club

The CGEB Journal Club was initially formed in 2007 by several postdocs/PIs in the Department of Biochemistry and has now expanded to include all CGEB labs’ trainees and faculty members who are interested in participating. These meetings are held on a bi-weekly basis throughout the year. Participants select and present a current research paper for discussion. A number of trainees have stated that this experience has been invaluable and an integral part of their overall training.

37 XIV. FUTURE DIRECTIONS

The main goals of the establishment of CGEB Centre were to: 1) advance the research programs of its members, 2) enhance recruitment/training of world- class postdocs and PhD students in CGEB labs, 3) promote collaborations between CGEB members, 4) leverage additional support for comparative genomics and bioinformatics research at Dalhousie, and 5) provide opportunities for seeking additional research funds from granting agencies through CGEB collaborations. From the progress described in this report, it should be clear that CGEB has already been spectacularly successful in advancing each of these goals. So a major future direction is, in fact, to do even more of the same!

Nevertheless, at our recent biannual CGEB members meeting, a number of future CGEB activities were proposed, including:

A. An annual CGEB poster session and social ‘mixer’, perhaps associated with the talk of one of the more eminent invited speakers in the CGEB Seminar Series. Now that CGEB has grown to 10 members and 67 trainees, it has become difficult for ‘everyone to know everyone’. This mixer would allow members, trainees (and the new ‘Associates’, see p. 8) to meet each other and discuss areas of mutual interest provoked by the poster session that could lead to future collaborations. A wine and cheese service would function as an added incentive for trainee attendance. Financing for this mixer could be drawn from the ‘New Opportunities Fund’.

B. An annual 2-3 day CGEB retreat with seminars/posters presented by CGEB members, Associates and trainees, as well as a handful of guest speakers (~70- 80 individuals). Ideally this retreat would occur offsite, perhaps in a remote resort hotel (e.g. Whitepoint Beach Resort). This way all of those involved are more likely to attend all talks and participate in all events and the intensity of the interactions is thereby increased. By inviting several high profile speakers with similar research interests, connections could be forged with these outside groups and give CGEB a higher international profile. This idea was stimulated by the apparent success of similar-style retreats coordinated annually by the Tula- funded Centre for Microbial Diversity and Evolution (CMDE) at UBC that were attended by new CGEB member Claudio Slamovits. Obviously, we would have to seek additional monies to support this annual activity as its projected cost (~$20,000/year) extends well beyond the current CGEB Budget.

C. Co-sponsorship of targeted workshops with the Canadian Institute for Advanced Research Integrated Microbial Biodiversity Program and the Canadian Institute for Health Research Institute of Genetics. Several potential hands-on workshops could be held to train those at CGEB in particular areas of interest. One potential workshop that is in the works (funded by CIFAR) focuses on the growing field of eukaryotic microbial genomics and genome annotation. All CGEB members could attend and learn ‘hands-on’ skills for assembling, annotating and analyzing whole eukaryotic genomes – a task that has been made affordable by the advent of cheap ‘Next Generation’ sequencing technology.

D. Co-sponsorship of a Phylogenomics Meeting. An international meeting involving experts in comparative genomics, phylogenetics and bioinformatics could be held at Dalhousie and some costs (e.g. invited speakers) could be offset by CGEB. A similar conference was held in Quebec a few years ago and was a resounding success.

APPENDIX A:

CGEB GOVERNANCE POLICY APPENDIX A: GOVERNANCE

Proposed Governance of CGEB

The purpose of CGEB is to stimulate research and collaboration among its members. The streamlined management structure we propose is designed to ensure fair and efficient operation. The organizational structure of CGEB will consist of a Deans Committee, a Director, a Steering Committee, and the Membership. The terms of reference for these bodies are outlined below.

I. DEANS COMMITTEE

The Deans Committee will meet annually with the Director, providing advice on operation and direction of the Centre, and identifying emerging opportunities for CGEB to advance its research and training goals at Dalhousie University. The Deans committee will be headed by the ‘Presiding Dean’ (initially the Dean of the Faculty of Medicine) and, with the other Deans, will be ultimately responsible for the Centre management and budget. The Presiding Dean will also advise the Director on matters relating to the operation of the Centre as issues arise. The Deans Committee will appoint new Directors in consultation with the Steering Committee and the CGEB Membership. The Deans Committee will consist of: Vice President, Research (or designate), ex-officio; Dean of Medicine (or designate), Presiding; Dean of Science (or designate); Dean of Computer Science (or designate).

II. DIRECTOR

The Director is ultimately responsible for decisions relating to Centre business and will chair the Steering Committee and supervise a Centre Administrator who will coordinate CGEB group meetings and meetings of the Deans Committee and Steering Committee, as well as prepare and receive Centre-related correspondence and assist in accounts-keeping. The Director will report to the Presiding Dean on all matters relating to Centre operation and budget and will meet with the Deans Committee annually. The Director position will normally be held for a three-year term but this term may be renewed on the recommendation of the Deans Committee. When required, a new Director will be selected by the Deans Committee, based on advice received from the CGEB membership.

III. STEERING COMMITTEE

The Steering Committee will be made up of the Director and two other faculty members in the CGEB group. The Steering Committee will be responsible for advising the Director on matters such as the disbursement of Tula Foundation-supported postdoctoral and graduate student positions to CGEB faculty, as outlined in the main text of the proposal. Furthermore, the Director will consult with the Steering Committee on any decisions substantially affecting CGEB before a final decision is made by the Director. The term for membership on the Steering Committee is three years, but reappointment of an individual whose term has been completed is possible providing the Membership approves.

IV. CGEB MEMBERSHIP

The CGEB Membership will have scheduled meetings bi-annually to discuss Centre business, and make/vote on recommendations to the Steering Committee and the Deans Committee regarding new CGEB members, nominations for Director, Steering Committee membership, and new opportunities for CGEB.

Proposed Composition of the Initial CGEB Management Structure

I. DEANS COMMITTEE • Vice President, Research (or designate), ex-officio • Dean of Medicine (or designate), Presiding • Dean of Science (or designate) • Dean of Computer Science (or designate)

II. DIRECTOR • Andrew Roger, Biochemistry and Molecular Biology

III. STEERING COMMITTEE • Andrew Roger, Biochemistry and Molecular Biology • Michael W. Gray, Biochemistry and Molecular Biology • W. Ford Doolittle, Biochemistry and Molecular Biology

IV. CGEB MEMBERSHIP • Andrew Roger, Biochemistry and Molecular Biology • Michael Gray, Biochemistry and Molecular Biology • Ford Doolittle, Biochemistry and Molecular Biology • John Archibald, Biochemistry and Molecular Biology • Alastair Simpson, Biology • Joseph Bielawski, Biology, and Mathematics and Statistics • Robert Beiko, Computer Science • Christian Blouin, Computer Science, and Biochemistry and Molecular Biology • Ed Susko, Mathematics and Statistics • (new) Assistant Professor, Biochemistry and Molecular Biology (job search underway)

Dr. Sunny Marche Associate Dean Faculty of Graduate Studies Dalhousie University

Dear Dr. Marche,

Re: Postdoctoral Fellows - Concerns and Issues for Inclusion at PDF Meeting in Ottawa

I was unavailable to attend the meetings where you asked for input in regulations regarding postdoctoral researchers that you will take forward to a meeting in Ottawa. In a letter dated October 27, 2008, my colleagues and I in the Centre for Comparative Genomics and Evolutionary Bioinformatics, outlined our points of view on many issues relevant to postdoc regulations at Dalhousie University. Although we did not receive a reply to our letter, we hope that the information and arguments we provided in that letter help to clarify the key importance of postdoctoral researchers and their training to the competitiveness of Dalhousie University as a research institution.

In lieu of attending the meeting you had on March 20th, I am writing this letter to re- emphasize some issues regarding postdoctoral researchers that I feel are extremely important to take forward to the discussion in Ottawa:

1) A large fraction (maybe more than 50%) of postdoctoral researchers in the biomedical and biological sciences at Dalhousie University (and most Canadian Universities) are not Canadians or landed immigrants. It is part of scientific culture to encourage Ph.D. students to explore postdoctoral research opportunities outside of their institution and often outside of the country as a way to broaden their horizons/experience and forge international collaborative connections. As a result, many Canadians travel to the US and Europe for postdocs, and many postdocs in Canada come from other countries. These postdocs significantly contribute to the research activities of our laboratories. They not only bring new ideas and techniques to Canadian labs, but, in exchange, they gain invaluable experience from the Canadian labs they are completing their postdocs in. It is therefore extremely important that whatever rules/legislations are adopted for postdocs in Canada, that they continue to allow easy access for non-Canadians to pursue their postdoctoral training in Canada. If, for instance, postdocs become classified as employees, then this could cause major problems with hiring foreign postdocs as each prospective supervisor would have to go through onerous and time-consuming HRDC screening to prove that a “Canadian” applicant was not equally qualified etc. This is inappropriate as the postdoctoral position is not a regular job; it is a training position. Furthermore, preventing foreign postdocs from coming to Canada will have terrible downstream negative consequences for competitiveness of Canadian researchers relative to their colleagues in the US and the EC. We would be deprived of opportunities to benefit from scientific knowledge from other countries, as well as future collaborative opportunities when the postdocs return to their home countries.

In case you are not convinced, I can tell you from personal experience that since 1999, I have supervised 16 postdoctoral fellows in my laboratory. Only three of the 16 are Canadian citizens -- the 13 others were foreign. Of the 16, three are currently in my lab as postdocs, nine have obtained full-time faculty positions at reputable universities and three of them are doing a second postdoc in Europe. I maintain mutually beneficial and productive research collaborations with seven of my former postdocs at universities in Canada, the US, Japan, Sweden and Spain. My own research successes, such as the award of an Alfred P. Sloan Foundation fellowship in 2004, a Peter Lougheed/CIHR New Investigator Fellowship in the same year and, most recently, an NSERC Steacie Fellowship in 2007, are in a large part due to my previous and current collaborative work with these excellent postdoctoral researchers from all over the world. I can honestly say that the synergy between my own expertise and that of the postdocs and graduate students that I have supervised was key to the success of my research group at Dalhousie and key to the ultimate success of these trainees in getting jobs.

2) The length of the postdoctoral training period should not be too short. The current rules for ‘academic’ PDFs at Dalhousie are too restrictive given that postdocs (especially ones in interdisciplinary environments) need a lot of time to gain the appropriate training to become effective researchers, fund-raisers, teachers and administrators. In our Oct. 28th letter, I outlined in detail the reasons for this. I would simply add here that, if a length limit were to be imposed, I would suggest a minimum of six years for a postdoc position. In previous group discussions you have hosted on this issue, you raised the question of why we even need postdocs – “shouldn’t a PhD be qualification enough?”, you asked. The answer is a definite “no”, and it is not because we are not training Ph.D. students properly. In biomedical/biological sciences, laboratory research takes a very long time and learning the theory and methods of a field takes both hands-on experience and critical review of the literature. Many postdocs are trying to branch-out from their PhD work to new sub- fields and learn new techniques (to diversify their research abilities). Add to those tasks, the need for a postdoc to: i) learn how to manage/supervise trainees in a lab setting (PI’s in biomedical science often have 8-10 trainees in total), ii) learn how to set up a lab, iii) learn how to write grants, iv) learn how to budget for research activities, and v) learn how to teach. It’s analogous to the situation with medical doctors. Why isn’t medical school enough? Why do they have to do 3-4 years of residency? I, for one, would not want to be operated on, by a student fresh out of medical school with no residency experience. I think an analogy like this might help the non-scientists at the Ottawa meeting understand the situation a bit better.

3) The issue of taxation of postdoc stipends. Aside from the serious problems associated with foreign postdocs being designated as employees, I believe that making postdoctoral fellowships taxable will seriously decrease our competitiveness at attracting world-class postdoctoral trainees to Canadian universities. For Canadians and landed immigrants, the benefits package (and CPP plus EI) may be seen as reasonable compensation for paying taxes. However, for the large fraction of postdocs who are non-Canadians, then the contributions are ultimately useless. For these individuals, having a tax-free income of $40,000/year (a typical postdoc salary) is extremely competitive with the remuneration available in the US and the EC. We have to realize that researchers in Canada are competing with these other countries to attract excellent postdoctoral trainees – so a competitive advantage in the size of stipends that we pay goes a long way towards attracting good people to Canada. This is especially important now that the US is injecting huge amounts of money into NSF and NIH. In Canada, operating grant funding for NSERC and CIHR has been undercut (and redirected) in the last federal budget.

4) Benefits. Assuming postdocs are not ultimately designated as employees, I strongly feel that the university should help negotiate a benefits package for postdocs. Graduate students have a benefits package and it is important that the same benefits are extended to postdoctoral researchers. Again, this is essential if we are to be competitive in attracting excellent postdoctoral researchers to Dalhousie.

5) Regulation of the postdoctoral training position. From our lab manager Katrin Sommerfeld who attended your March 20th meeting in the Kellogg Library, I learned that you made a suggestion that the postdoctoral training process become more regulated or structured. I must admit that I am wary of any further complexities being introduced into postdoctoral research training. The postdoc period is one of the only times in a researcher’s life when he/she can fully devote him/herself to doing research and learning the ‘ropes’ of day to day scientific management without endless interruptions in the form of teaching, meetings, courses, committees, etc. Furthermore, faculty members who supervise postdocs already spend a lot of time in activities supporting the “structured” training of undergrads and graduate students (i.e. teaching graduate courses, attending graduate student presentation courses, thesis supervisory committees, etc.). The training of a postdoc is thankfully free of this structure. The ‘advanced’ level of the training required for postdocs benefits from flexibility and it should be tailored to the individual needs of the trainee. Certainly, offering seminars/courses on professional development for postdocs (such as the one you teach) is a welcome enrichment to the postdoc training experience. However, formalizing the training beyond this is both undesirable and unnecessary. Please keep in mind that although some postdoc supervisors may not be doing a ‘good job’, many of us put a lot of effort into this kind of training; these efforts and abilities should not be ignored. Researchers raise the funds that support the stipends of postdocs and their research activities. It is important that we have not only this responsibility, but also the authority to carry out the training in a way that maximizes mutual benefit to the postdoc and the research program we are managing.

Sincerely yours,

October 27, 2008

Dr. Carolyn Watters, Dean Dr. Sunny Marche, Associate Dean Faculty of Graduate Studies Dalhousie University

Dear Dr. Watters and Dr. Marche,

We are writing to you regarding the new “PDF Policy and Procedures” that the Faculty of Graduate Studies has implemented, partially in response to the changes in the income tax status of postdoctoral fellows. While we are pleased that FGS is taking a proactive role in enhancing the postdoctoral training environment of the university, we are concerned that the new PDF policy was developed with limited initial input from faculty members, who are the primary educators of postdoctoral trainees and who, for the most part, pay their stipends from their research grants.

The change in the Income Tax Act that allows PDFs to claim their stipends as non-taxable fellowship award income is a great opportunity to make postdoctoral training in Canada more attractive to excellent candidates worldwide. Dalhousie’s research community could potentially benefit from this new policy. However, because the FGS PDF policy in its current form does not reflect the diversity of the requirements of postdoctoral fellowships in the different fields of research at Dalhousie (in particular in the life and biomedical sciences), it will have a serious negative impact on our competitiveness in attracting the best PDFs to our university and retaining them.

Our chief concerns with the policy are that: i) it specifies an overly restrictive ‘three year from PhD completion’ eligibility requirement for PDF candidates, ii) the overall length of the academic PDF tenure is far too short, and, iii) the distinction between academic PDFs and research PDFs is artificial and creates an unfavourable ‘two tier’ system. Below we explain in detail the difficulties with these aspects of the PDF policy and the changes necessary to improve it.

1) Eligibility of candidates for postdoctoral fellowships at Dalhousie. The new PDF policy states that: “Individuals who have completed a Ph.D. within three years from the date of application…., are eligible for consideration as an academic PDF or a research PDF…..”

There are several problems with these requirements. First, many excellent candidates for PDFs in our research groups will exceed the 3-year eligibility limit. This is because it is becoming standard in the life/biomedical sciences for PDFs to complete several multi-year postdoctoral stints in different laboratories or industry. This is not simply because PDFs cannot find jobs within the first three years, rather it is because a productive career in competitive biomedical research nowadays often requires that PDFs master a number of different subfields and gain experience in a number of different research environments. Moreover, completing multiple postdoctoral stints is likely to become more and more common as the funding opportunities and competitiveness in inter-disciplinary research increase.

The research environment in the biomedical sciences also reflects this changing reality for postdocs. In the biomedical sciences, professors not only teach, conduct research and become involved in administration, they also typically spend a substantial amount of time and effort in managing their research group. Biomedical research is often accomplished by large teams (often >10 trainees/group) managed by the faculty member. To sustain these activities and equip his/her research facilities the faculty member must also spend a substantial amount of time applying for grant funding from multiple sources. Since the grant award success rates at agencies such as the Canadian Institutes of Health Research (CIHR) have dipped as low as 13%, this means that repeated attempts are usually made before a grant is secured. The training of a PDF in the biomedical research setting includes preparation for leading group projects, learning how to prepare competitive grant applications, and developing mentoring skills through helping in supervision of undergraduates and graduate students involved in the group projects. As a result, it often takes more than one three-year postdoctoral fellowship for an individual to not only carry out their independent research and publish it in reputable journals, but also develop the grantsmanship, supervisory skills and independence sufficient to be able to function as a successful faculty member.

Indeed, current job searches in biomedical departments often ‘pass over’ those with only a few years of postdoctoral experience in favour of individuals with longer and more diverse PDF experiences. To give an example, a minimum requirement of at least two years postdoctoral experience was specified in the advertisement for an entry-level probationary tenure-track position in a recent job search by the Dept. of Biochemistry and Molecular Biology. Several of the excellent candidates who had completed even three years of postdoctoral study were seen by the search committee as too inexperienced to handle the full responsibilities of a biomedical research-intensive faculty position. The top candidate (who was offered and subsequently accepted the position) had a total of six years of postdoctoral experience obtained at a Canadian university. Under the current PDF policy at Dalhousie it would not have been possible for an excellent researcher such as this individual to have completed comparable postdoctoral training at Dalhousie after the first three years of his PDF. Yet this is exactly the type of top-notch young scientist we wish to attract and train as a postdoctoral fellow.

Note that the Dalhousie ‘three years out of PhD policy’ for eligibility is actually more restrictive than the eligibility requirements for postdocs being paid from CIHR operating research grants (the CIHR limit for starting a postdoc is within five years of obtaining a doctoral degree and there is no limit on subsequent duration). Furthermore, other granting agencies and foundations (e.g. the Tula Foundation discussed below) do not have any eligibility limit. Since many other Canadian universities will not institute PDF eligibility requirements (or they will make requirements more in line with the granting council guidelines), they will have an advantage in recruiting the excellent PDFs that are ineligible to complete postdoc fellowships at Dalhousie University under this new policy.

2 Finally, we would like to question the rationale of PDF eligibility limits beyond the straightforward requirement of a doctoral degree. If an individual has a Ph.D. from a reputable institution and seeks postdoctoral training under a faculty researcher at Dalhousie University, and that faculty member is willing, and permitted (under granting agency guidelines) to pay their fellowship stipend, why should FGS impose arbitrary eligibility rules that disqualify the candidate? What purpose do these eligibility rules serve? It seems more appropriate that the faculty member responsible for supervising the postdoc, and funding his/her stipend, should also have the authority to decide if that candidate has the appropriate background for the position of a PDF in his/her research group. Eliminating eligibility rules like these would have the added benefit of saving the time and efforts of the FGS staff currently responsible for reviewing various aspects of the PDF applications to ensure they meet the requirements.

2) The time restriction on academic PDFs and the artificial distinction between academic and research PDFs.

A second, and equally serious problem with the current PDF policy concerns the length of the academic postdoc tenure and the designation of two classes of postdocs. According to the policy, postdoctoral researchers are eligible to be academic postdocs for only three years at Dalhousie. After that time, they must either leave, or their position can be ‘renewed’ but at that point they may only stay on as a research postdoc for a maximum of three more years. Clearly the motivation for erecting these two classes is related to the Canada Revenue Agency’s discussion of postdoc fellowships in the interpretation bulletin, IT75R4, of the Income Tax Act. In parts 11 and 12 of this bulletin a distinction is made regarding the primary purpose of a fellowship for doctoral and postdoctoral candidates. If the “primary purpose of the award is to further the education and training of the recipient in his or her individual capacity…” then the fellowship stipend is an award and is not taxable income. If, on the other hand, the “primary purpose of the award is to carry out research for its own sake….the award is considered to be a research grant….” and the doctoral candidate or postdoc must report his/her stipend as taxable income. Clearly, the former type of trainee coincides with the concept of an ‘academic PDF’ and the latter with a ‘research PDF’ as outlined in the PDF Policy (pg 2). Note, however, that the CRA documentation does not explicitly suggest such a classification be made at the educational institution. Furthermore, CRA’s policy applies equally to the activities of both doctoral and postdoctoral candidates.

Unfortunately, interpreting the CRA regulations is difficult since, in reality, doctoral students and PDFs carry out research both for the purposes of furthering their own education/training and for the sake of advancing research: there is no natural dividing line between these two goals and neither is obviously primary. FGS has clearly decided to deal with this problem with regard to doctoral candidates by classifying them all as ‘academic’. However, for postdocs, the PDF policy instead makes an artificial distinction between ‘academic’ and ‘research’ streams that coincides with a three-year limit for the former before re- classification as the latter. As we have argued above, a three-year limit on postdocs is unreasonable when considering the reality of what many PDFs must learn to become trained for the next stage of their careers in the life and biomedical sciences. Furthermore, the classifications of ‘academic’ and ‘research’ PDFs will be extremely detrimental to a healthy training environment. For example, consider an excellent PDF who, in order to get the most out of her training at Dalhousie (i.e. her research project is by necessity longer term or she needs to learn more skills), has decided to continue her postdoc for a total of 4-5 years. The

3 supervisor also feels this extension is important and wishes to renew the postdoc for years 4-5. Here is the problem. Assuming the stipend is ~$40,000/year, in year 3, the fellowship income the postdoc receives incurs no tax. In years 4 and 5, however, at a time when the postdoc has more training/expertise than when she started, her income becomes taxable and now her take-home pay (after tax) falls to roughly ~$35,000. In effect, the postdoc is doing the same work as before but now, with even more experience under her belt, is effectively making ~$5000 less. This policy is a very poor way to reward this PDF for her excellent work and, in practice, it will be extremely demoralizing. Those PDFs who are supporting families are likely to be even harder hit under these circumstances. Furthermore, if they are working in a lab with academic postdocs, research postdocs become ‘second-class citizens’ whose take-home pay is substantially less than the other PDFs, despite their greater knowledge and experience.

Another undesirable result of the above policy is that supervisors will feel pressured to increase the stipend of the research PDF in years 4+ to compensate for the lost income relative to years 1-3. However, many researchers do not have sufficient grant funds to accommodate this. Those who do stand to lose precious research dollars (~$6000- $7000/year to compensate for the loss) from their grants, research dollars that were not originally designated to be used for this purpose. One might be tempted to suggest that researchers might pay academic postdocs $5000 (or so) less to begin with and then increase the pay to research postdocs to avoid this situation. However, under these circumstances we would lose the competitive edge relative to other Canadian universities that the new tax legislation provides, because our starting postdoc stipend offers would be very low. Furthermore, some granting agencies stipulate minimum PDF stipends limiting how low initial offers can be (e.g. CIHR lower limits on PDF stipends are $36,750 p.a.).

The problems described above can be avoided if, as was decided in the case of doctoral students, FGS were to designate all PDFs as ‘academic postdocs’ whose primary purpose is to advance their education/training and do away with the 3-year length restrictions on academic postdocs. We see no real justification for a limit on postdoc lengths: CRA certainly does not specify anything like this in the agency’s fellowship bulletin and it is far from clear what purposes these limits serve. If one purpose is to prevent unscrupulous exploitation of junior personnel by discouraging their timely application for independent positions, there must be better, case-by-case ways of dealing with this concern (if it is indeed a justified one), possibly through the creation of a postdoc ombudsman or the formation of postdoc unions. It is our position that faculty members responsible for paying and training PDFs are themselves in the best position to decide how long a PDF should last. This is the system that Dalhousie has operated with for years and that has presumably contributed to its ranking by The Scientist as one of the best places in the world for postdoctoral training. We should not try to fix something that is not broken.

If FGS deems that a limit is really needed, then we suggest that it should be minimally restrictive so as to maximize flexibility and enhance Dalhousie’s competitiveness for PDF recruitment relative to other Canadian and American universities. A maximal length of eight years would be reasonable and would avoid over-burdening FGS staff with repeated renewal exception requests. Furthermore, special attention should be paid to non-Canadian postdocs (who make up a large fraction of the life science/biomedical PDFs at Dalhousie) who must obtain a special work permit and cannot be designated as research associate employees.

4 Finally, we would like to explain why we feel this issue is so important. As members of the newly minted interdisciplinary Centre for Comparative Genomics and Evolutionary Bioinformatics (CGEB, see http://www.cgeb.dal.ca), we have had the good fortune to receive a sizable grant (>$3,000,000 over eight years) from the Tula Foundation (see attached letter from Dr. Eric Peterson, President of the Tula Foundation). More than half of these monies are dedicated to postdoctoral fellowships, each of which may last as long as five years, with the eligibility of candidates to be entirely decided at the discretion of CGEB researchers. This grant was offered to the CGEB group in recognition of the internationally renowned accomplishments of our research teams over the past decades. The grant is meant to strengthen our ability to attract and train world-class postdoctoral fellows and Ph.D. students. The FGS PDF policy was implemented after these monies were awarded and we feel that the issues identified and discussed above could have a serious negative impact on our ability to achieve our research and training goals. It is especially problematic for us because the fields of genomics and bioinformatics are explicitly interdisciplinary and often require PDFs from diverse career paths and backgrounds, and who need extra time as postdocs to master several fields. Importantly, we are concerned that the overly restrictive PDF policy may hamper our chances of receiving additional monies from the Tula Foundation in the future.

To summarize, all postdoctoral trainees and faculty members at Dalhousie University would be best served by a PDF policy that is flexible with respect to eligibility requirements, does not unduly restrict the length of postdoctoral training periods, enriches the PDF training experience, and maximizes a PDF’s chances to succeed in his/her chosen career. We ask that you carefully consider our arguments above and act to modify the FGS PDF policy along these lines.
