Understanding and improving photosynthesis
My long-term research goals are to understand how photosynthetic energy conversion works, how it is regulated, and how it might be improved to help meet the world’s needs for food, fuel, and carbon sequestration. Our research focuses on photoprotection, improving photosynthesis, and carbon dioxide removal using plants and microalgae.
Algal biology
Eukaryotic algae and cyanobacteria (often collectively referred to simply as “algae”) are relatively simple phototrophic organisms that carry out oxygenic photosynthesis similar to that in land plants. Algae are amazingly diverse in terms of habitat, biochemistry, physiology, and morphology, and they have critical roles in global ecology and biogeochemistry. Aquatic microalgae (phytoplankton) are responsible for approximately half of the net primary production of organic matter on Earth, and they have recently re-emerged as potential next-generation feedstocks for biofuels (http://www.pbs.org/wgbh/nova/tech/algae-fuel.html).
