We study the ecology and physiology of photosynthetic organisms in marine ecosystems. Our lab focuses on phytoplankton, the unicellular algae that are responsible for nearly all photosynthesis in the ocean, salt marsh plants, and corals. Recent research has included studying the effects of climate change on phytoplankton and the metabolites they produce, investigating the taxa responsible for primary production on coral reefs, and developing methods to map marine ecosystems such as salt marshes and coral reefs.
