    "Proton-Coupled Electron Transfer:
    Moving Together and Charging Forward
    "

    ABSTRACT

    Proton-coupled electron transfer (PCET) reactions play a vital role in a wide range of chemical and biological processes. In these reactions, an electron and a proton move in a coupled manner because of electrostatic interactions. The electron and proton could transfer in the same direction or in opposite or perpendicular directions. Moreover, PCET reactions may be sequential, where either the electron or the proton transfers first to produce a stable intermediate, or concerted, where they transfer simultaneously without a stable intermediate. My group has developed a general theory to describe all of these types of PCET reactions and have applied this theory to PCET in solution, proteins, nanoparticles, and electrochemistry. This theory has assisted in the interpretation of experimental data and has provided experimentally testable predictions. The insights from this theory are guiding the design of more effective molecular catalysts, artificial photosynthesis systems, energy conversion devices, photoreceptor proteins that use light to control biological processes, and enzymes that are essential for DNA synthesis and repair.

    CITATION

    • For expertise in the development and application of theoretical and computational methods for describing chemical reactions in condensed phases and at interfaces.
    • For breakthrough research on proton-coupled electron transfer (PCET) reactions and enzymatic processes that have provided new strategies for designing light harvesting assemblies for solar energy conversion.
    • For studies using PCET of the excited state properties of inorganic complexes with implications for artificial photosynthesis, charge transfer dynamics, and quantum mechanical effects in chemical, biological, and interfacial processes.

     

    BIOGRAPHY

    Sharon Hammes-Schiffer received her B.A. in Chemistry from Princeton University in 1988 and her Ph.D. in Chemistry from Stanford University in 1993, followed by two years at AT&T Bell Laboratories. She was the Clare Boothe Luce Assistant Professor at the University of Notre Dame from 1995-2000 and then became the Eberly Professor of Biotechnology at The Pennsylvania State University until 2012, when she became the Swanlund Professor of Chemistry at the University of Illinois Urbana-Champaign. Since 2018, she has been the John Gamble Kirkwood Professor of Chemistry at Yale University. Her research centers on the investigation of proton-coupled electron transfer, nonadiabatic dynamics, and quantum mechanical effects in chemical, biological, and interfacial processes. Her work encompasses the development of analytical theories and computational methods, as well as applications to experimentally relevant systems. She is a Fellow of the American Physical Society, American Chemical Society, American Association for the Advancement of Science, and Biophysical Society. She is a member of the American Academy of Arts and Sciences, the U.S. National Academy of Sciences, and the International Academy of Quantum Molecular Science. She has received the American Chemical Society Award in Theoretical Chemistry, the Royal Society of Chemistry Bourke Award, and the Joseph O. Hirschfelder Prize in Theoretical Chemistry. She is currently the Editor-in-Chief of Chemical Reviews and is on the Board of Reviewing Editors for Science. She has over 300 publications and has given more than 430 invited lectures.


    Attendance is limited to 200 people. People registering later will be put on a wait list.
