Welcome to the 2016 Astrobiology Graduate Conference

On behalf of the entire AbGradCon 2016 Organizing Committee, we would like to extend a heartfelt welcome to all participants in the 2016 Astrobiology Graduate Conference at the University of Colorado Boulder. AbGradCon is a unique and exciting opportunity - a meeting organized by and for early-career researchers in all ﬁelds of astrobiology. This year’s conference features contributions from more than 80 participants in an incredible diversity of ﬁelds: astronomy, chemistry, biology, biochemistry, geology, planetary science, education, mathematics, information theory, and engineering. We’ve come together in Boulder, Col- orado, nestled in the foothills of the Rocky Mountains, to share our enthusiasm and our passion for astrobiology.

AbGradCon is a chance for us to come together to share our research, collaborate, and network, without the pressure of senior researchers. AbGradCon 2016 marks the twelfth year of this conference–each time in a different place and organized by a different group of students, but always with the original charter as a guide. These meetings have been wildly successful both when connected to Astrobiology Science Conference (AbSciCon), and as stand-alone conferences. Since it is organized and attended by only early-career researchers, AbGradCon is an ideal venue for the next generation of career astrobiologists to form bonds, share ideas, and discuss the issues that will shape the future of the field.

We hope that this, the 12th incarnation of AbGradCon, will prove as fruitful an experience for all our participants as it has for us in the past. Serving on the Organizing Committee has been a challenging, but extremely rewarding experience. We hope your experiences here this year will motivate many of you to return in future years, both as participants, and as members of the Organizing Committee. As with any endeavor which relies on a new group of leaders with each iteration, there are bound to be bumps in the road. Please do not hesitate to reach out to any member of the Organizing Committee should you have any questions – we are committed to making this conference a resounding success!

All Day Departures Invited Guests

Irena Mamajanov is a Professor in the Earth-Life Science Institute (ELSI) at the Tokyo Institute for Technology. She is a spectroscopist interested in systems chemistry, polymer science and biomimetics. Dr. Mamajanov has been involved in origin of life research since her PhD program at Brandeis University where she worked under the tutelage of Judith Herzfeld on the structure elucidation of hydrogen cyanide polymers via solid state NMR. Upon completion of her PhD program, Dr. Mamajanov took a postdoctoral position in Nicholas Hud’s lab at the Georgia Institute for Technology, which led to a full research scientist position there. Her in- terests shifted towards condensation polymerizations, such as the synthesis of nucleic acids, peptides and polysaccha- rides under thermodynamically unfavorable water solution conditions.

In 2014, Dr. Mamajanov was awarded Simons Foundation Collaboration on the Origin of Life fellowship. She then moved to Carnegie Institution of Washington to conduct her research on the origin of prebiotically plausible protein analogs. Dr. Mamajanov joined ELSI in January 2016. She has since been leading a research group studying so-called messy chemistry. The group includes chemists, theoretical physicists, instrumental analysis experts and computer scientists. The goal of this effort is to understand the structure, behavior and emergent properties of complex prebiotically plausible reaction networks. Additionally, Dr. Mamajanov chairs the organizing committee of the upcoming ELSI Symposium that is to take place in January 2017. Alexis Templeton is the Principal Investigator of the Rock-Powered Life NASA Astrobiology Institute team and a professor of geomicrobiology in the Department of Geo- logical Sciences at the University of Colorado at Boulder, where she has been on the faculty since 2005. Dr. Temple- ton?s fields of expertise include microbe/mineral interac- tions, biomineralization, chemical imaging, spectroscopy, and isotope geochemistry. Dr. Templeton directs research focused on defining the pathways and products of abi- otic and microbial electron-transfer processes in laboratory systems, and she is actively engaged in serpentinization field studies based in Oman, as well as sulfur biomineralization field studies on Ellesmere Island, Canada that have relevance to Mars and Europa. The Templeton lab has previously conducted research on thermophilic metal-cycling organisms in the deep subsurface at Henderson Mine, Colorado, and on submarine bioalteration of oceanic crust at Loihi Seamount, Hawaii and Vailulu?u Seamount, American Samoa.

Dr. Templeton earned a B.A. and M.S. in Earth Sciences at Dartmouth College in the area of isotope geochemistry, which led to technical position at Lawrence Berkeley National Lab- oratory applying isotope techniques to bioremediation efforts. She then pursued a PhD in Earth Sciences, specifically the new field of geomicrobiology, at Stanford University, followed by a NSF Postdoctoral position in Marine Biology at Scripps Institution of Oceanography. In her PhD and postdoc, Dr. Templeton developed expertise in synchrotron based x-ray spectroscopy, chemical dynamics in biofilms, and the cultivation of metal oxidizing organisms that inhabit rock-hosted ecosystems, which then shaped the research directions she has pursued in her current faculty position at CU Boulder.
