Research Interests

I am interested in how the biology of the oceans affects global biogeochemical cycles. My current research focuses on how marine phytoplankton are responding to global change. Specifically, I am studying coccolithophores, a type of calcifying phytoplankton that are widespread and influence global carbon cycling. Calcifying organisms, such as coccolithophores, can be especially susceptible to changes in ocean chemistry from anthropogenic carbon emissions (ocean acidification). I use oceanographic data and Earth System Models to improve projections on how coccolithophore populations and marine ecosystems may change with further warming and ocean acidification.
