Area of Interest

My laboratory seeks to reveal Nature’s molecular blueprint for sustainable solar-to-chemical energy transduction, and to regulate and improve the efficiency of photosynthesis. By combining techniques from molecular biology, protein biochemistry, spectroscopy, and instrument design, we aim to elucidate the mechanisms used by cyanobacteria, algae, and plants to generate O2 from water and sunlight.
