I am an ecologist who studies planktonic organisms in marine and fresh waters. My research emphasis is on protists (algae and protozoa) and their trophic interactions. A continuing thread in my research is the physiology and ecological importance of mixotrophic protists that are both photosynthetic and phagotrophic. See my website for recent publications and teaching.
