My Research

The oceans teem with marine microbes that move at the mercy of currents. These microbes are largely invisible to the naked eye, but have huge impacts on how food webs function and how elements are cycled throughout the planet. My research is dedicated to studying these amazing microbes and the processes they influence.

CO2 entering the ocean from the atmosphere is fixed into organic carbon by phytoplankton in the surface ocean. The produced organic carbon fuels marine food webs, but a portion can also make its way or be exported deep into the ocean interior where it is separated from the atmosphere for centuries to millennia. This vertical export of organic carbon is a major mechanism by which the ocean can act as a buffer to increasing human CO2 emissions.



My research interests:

I’ve approached these questions by collaborating with a diversity of marine scientists to collect and synthesize biogeochemical, bio-optical, remote sensing, and experimental data.
