InterestsI specialize in field observations and age-based assessments of estuarine fisheries of coastal and shelf molluscs. The biology of these molluscs (Scallops, Ocean Quahogs, and Surf Clams) are temperature sensitive and are used as a barometer of climate change. Growth signatures found in the valves of these shellfish are used to age while C14 samples are taken and analyzed to date each organism. Trends found may be related to climate change and may be responsible for the temporal and spatial recruitment of the species.
