Area of Interest
Our laboratory investigates the chemical mechanisms used by plants and some microbes to convert solar energy to chemical energy through photosynthesis. We apply techniques from molecular biology, biochemistry and spectroscopy to track the assembly and function of the protein machinery that makes molecular oxygen, O2, from water and sunlight.
