REsearch Interests
My research is motivated by how phytoplankton will acclimate and adapt to changing climate. Phytoplankton are responsible for about half of photosynthesis on the planet, making them key players in the global carbon cycle. With rising atmospheric CO2, warming, and shifting nutrient limitation in the ocean, they face a myriad of changes to their environment. Which phytoplankton adapt and become dominant will be important in determining the efficiency of carbon sequestration and the structure of the marine food web. My research uses physiology, genetics and modeling to forecast the winners and losers in the aftermath of this significant global change.
