My research focuses primarily on phytoplankton and aquatic microbial ecology, including harmful algal blooms and the role of phytoplankton in the global carbon cycle. I have over 25 years of aquatic cytometry experience and use cytometry,
single cell sorting and genomics to examine phytoplankton and bacterioplankton in aquatic environments across the globe. My interdisciplinary work combines biological, chemical and physical oceanography and leverages both laboratory and field
work at sea. I received my BS in Biological Sciences at Virginia Tech in 1993 and my Ph.D. in Biological Oceanography from the Massachusetts Institute of Technology/Woods Hole Oceanographic Joint Program in 2001, where I studied phytoplankton
ecology, specifically in the area of toxic algal blooms in the Gulf of Maine using flow cytometric methods. My interests in marine microbes and flow cytometry led me to Bigelow Laboratory for Ocean Sciences, a non-profit organization in mid-coast
Maine, where I am a Research Scientist and since 2014 the Director of the Center for Aquatic Cytometry. I am very active in education and public outreach and teach both introductory and advanced courses in aquatic cytometry.
