My research is broadly focused on the biological oceanography of coastal seas, especially the Gulf of Maine. More specifically, I am interested in physical-biological coupling of phytoplankton, zooplankton, and larval fishes. In the past, these interests have lead me into detailed studies of larval herring dynamics in the Gulf of Maine, larval cod dynamics on Georges Bank, phytoplankton blooms dynamics, the spring bloom and nutrient dynamics on Georges Bank, and biological production (in the broadest sense) of Maine's estuaries. My current research projects are focused on phytoplankton, nutrients and red tides in the Gulf of Maine. Most of my work is heavily dependent on shipboard oceanographic surveys, as opposed to land-based laboratory experiments. I prefer to approach specific research problems in an interdisciplinary manner and to propose solutions to those problems that require the formation of teams of researchers that include physical, chemical and biological oceanographers.
