Understanding how environmental factors affect animal performance (survival, growth and reproductive success) is important to our understanding of the natural world and how human activity affects it. My laboratory is interested in the environmental and endocrine control of osmoregulation, growth, migration, development and reproduction in teleosts, primarily anadromous fishes. Our current research focuses on physiological and environmental factors that affect conservation, restoration and enhancement of Atlantic salmon, American shad, blueback herring, alewife and Atlantic sturgeon. This includes laboratory and field work on underlying physiological principles and capacities, and applied work on contaminants, hatcheries, dams and with wild populations.
