Overview
Personal Profile
Paul King's research interests are broadly in the study of photobiological and artificial photosynthetic systems for converting solar energy into biofuels. Specific areas of interest include using molecular, biochemical and biophysical techniques to investigate the catalytic mechanisms and structure-function of hydrogenases; bioenergetics of hydrogen metabolism in model green algae and anaerobes; and the photochemical processes that control photon conversion to reduced chemicals in enzyme-based hybrid complexes. These efforts seek to develop a fundamental understanding of the mechanisms underlying energy transduction networks in photobiological and photochemical systems. Paul's long-term goal is to apply knowledge on the basic principles of biological energy conversion towards advancing solar conversion technologies for renewable energy applications.
