This document was produced under contract number DE-AC05-060R23100 between the U.S. Department of Energy and Oak Ridge Associated Universities. 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 second biennial meeting of the Principal Investigators (PIs) funded by the Photosynthetic Systems 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, Photosynthetic Systems and Physical Biosciences. These two Biosciences programs, along with a strong program in Solar Photochemistry, comprise the current Photochemistry and Biochemistry Team. This meeting specifically brings together under one roof all of the PIs funded by the Photosynthetic Systems program, along with Program Managers and staff not only from DOE BES but also other offices within DOE, the national labs, and other federal funding agencies. Our goal in holding these research meetings is to provide an environment that fosters exchange of information on your DOE-funded work; facilitates cooperation and collaboration among research groups; provides opportunities for discussions with DOE Program Managers and staff; and promotes sharing of new ideas and methodologies. Accordingly, “down time” is scheduled to encourage informal discussions and interactions. This year’s agenda features two invited speakers. We are pleased to have Dr. John Turner from the National Renewable Energy Laboratory who will talk about hydrogen production from photoelectrochemical cells (PECs), providing “food for thought” regarding the economic and theoretical considerations of PECs. We are also delighted to have Dr. W.E. Moerner from Stanford University who will tell you about exciting developments in the use of Anti- Brownian ELectrokinetic (ABEL) trap technology to understand behavior of individual photosynthetic antenna proteins and redox enzymes. While we extend a warm welcome and our sincere appreciation to our invited speakers, the real star at this year’s meeting is you. Your productivity, creativity, and commitment to world-class science come across in your abstracts and not only make a meeting like this possible but also gratifying and enjoyable. We hope that the meeting will further enhance the innovation and success of your research efforts and build a robust community of researchers in the study of photosynthesis and energy capture, conversion, and storage in plants, algae, and photosynthetic microbes. Whether you are delivering a talk or presenting a poster, we sincerely appreciate your contribution to this meeting. It has been an extraordinary time in DOE’s Office of Science, and we also thank you for your many contributions to the successful execution of our many funding opportunities over the last few years. Finally, we thank Diane Marceau and Dawn Adin from DOE BES and Connie Lansdon, Tim Ledford, and Verda Adkins-Ferber from Oak Ridge Institute for Science and Education (ORISE) for their invaluable help in planning and successfully executing the many logistical tasks associated with this meeting.
