Judy is interested in coastal ecology, phytoplankton dynamics, and interactions between bivalve shellfish aquaculture and the environment. Working with her colleagues at the Milford Laboratory, her research examines the variability in coastal environments on various time scales and how such variability affects shellfish in nature and vice versa. She uses tools such as long term unattended measurements, flow-cytometry, phytoplankton variable fluorescence, and HPLC pigments to study phytoplankton community composition. One of her current projects is aimed at developing correction algorithms to improve the accuracy of phytoplankton biomass measurements collected by commonly used in vivo chlorophyll fluorescence sensors. Additionally Judy is interested in the ecology of sugar kelp aquaculture.
