Photosynthetic Light Harvesting

Photosynthesis Research Schematic

Our group works to understand and control biological photosynthesis through site-specific mutagenesis in photosynthetic proteins. On the one hand, this work targets a quantitative understanding of native photosystem function at the molecular level, especially the optical properties and functional role of the many chlorophyll ligands bound by each photosynthetic protein. On the other hand, understanding native function opens the door to mutation-based optimization. Although native photosynthetic proteins are extremely effective at their native function—providing energy for the growth and survival of the organism—they are remarkably inefficient at the large-scale energy conversion needed for biofuel production. Our research aims to bridge this gap via targeted mutagenesis in wild-type proteins.

To acheive these goals, targeted mutation studies are complemented by high-resolution spectroscopy and mixed quantum/classical simulation and theory. Follow the links to learn more about these research areas or scroll down for publications related to photosynthesis.
