Research Areas

I am a marine ecologist and biological oceanographer. My research interests span marine plankton ecology from organismal to population and community levels. Plankton form the foundations of marine food webs. Complex interactions exist among plankton as well as between plankton and the physical/chemical environment. To understand these patterns and processes, I employ experimental (e.g., controlled laboratory bottle experiments), observational (e.g., net tow sampling and Unmanned Aerial Research Vehicle – UARV – surveys), and molecular approaches in data collection. Current projects include: distribution and diversity of Sargassum and its associated community; and plankton-microplastic interactions.
