Research summary


Life on our planet is driven by Photosystem II that captures sunlight and extracts electrons from H2O to reduce CO2 into sugars while releasing the O2 we breathe. My laboratory concentrates on structure-function studies of Photosystem II in plants and cyanobacteria. Currently we are working on protein-protein interactions that facilitate sustained water-splitting activity by Photosystem II in response to changing environmental conditions such as fluctuating light levels, temperature and pH. We are also interested in protein factors that are required for the assembly of Photosystem II. Since the sun provides more energy in 1 hour than our entire global energy consumption in 1 year, we are also working on metabolic engineering to couple the harvesting of light by photosynthetic protein complexes to the efficient production of biofuels in cyanobacteria.
