The research grants and contracts described in this document are, unless specifically labeled otherwise, supported by the U.S. DOE Office of Science, Office of Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences Division. ii Foreword This volume provides a record of the 2nd biennial meeting of the Principal Investigators (PIs) funded by the Physical Biosciences program, and is sponsored by the Chemical Sciences, Geosciences, and Biosciences Division of the Office of Basic Energy Sciences (BES) in the U.S. Department of Energy (DOE). Within DOE-BES there are two programs that fund basic research in energy-relevant biological sciences, Physical Biosciences and Photosynthetic Systems. These two Biosciences programs, along with a strong program in Solar Photochemistry, comprise the current Photo- and Bio- Chemistry Team. This meeting specifically brings together under one roof all of the PIs funded by the Physical Biosciences program, along with Program Managers and staff not only from DOE-BES, but also other offices within DOE, the national labs, and even other federal funding agencies. Of course we also have some distinguished speakers who we hope will stimulate your thinking, and inform you about new tools and resources that will allow you to meet - or exceed - your current research objectives; more on that below. Our objective in holding these research meetings is to provide an environment that (1) encourages free exchange of information on your DOE-funded work; (2) facilitates new collaborations between individual research groups with complementary strengths; (3) allows opportunities for discussions with DOE Program Managers and staff; (4) exposes you to new ideas and methodologies; and (5) supplies information on DOE User Facilities, and how one goes about gaining access to them. In that regard, this year’s agenda features several invited speakers from the DOE national labs. We are delighted to feature Allen Orville from Brookhaven National Laboratory as one of our featured “idea- generators” on the physical science side, and Bryan Linggi and John Cort from the Pacific Northwest National Laboratory (PNNL) who will tell you about the exciting “-omics” capabilities at PNNL’s Environmental Molecular Sciences Lab (EMSL) – and how one goes about accessing them. Ian Carmichael from the Notre Dame Radiation Laboratory has also been invited to provide a brief talk on how he and his colleagues are trying to address the serious problem of radiation damage to protein structures that is caused by x-ray beam lines, and why it is a critically important problem to address. While we extend a warm welcome and our sincere appreciation to our invited speakers, the real star at this year’s meeting is…you. It is your hard work, creativity, productivity, and commitment to world- class science that comes across in your submitted abstracts. Whether you are delivering a talk or presenting a poster, we are sincerely appreciative of your contribution to this meeting. The depth and breadth of the DOE-BES Biosciences portfolio is what makes a meeting like this not only exciting, but also – we hope – a very fun and rewarding one to attend. It has been an extraordinary period of time in DOE’s Office of Science, and we want to thank you for your many contributions to the successful execution of the many calls we have put out over the last two years. Finally, we also wish to thank Diane Marceau from DOE-BES and Connie Lansdon from Oak Ridge Institute for Science and Education (ORISE) for their invaluable help in planning and successfully executing the many logistical tasks associated with putting on this meeting.
