As a toxicologist, I am interested in the fate and effects of contaminants in aquatic ecosystems, including the effectiveness and toxicity of methods to control the spread of non-indigenous species of critical importance to the health of the nation’s aquatic resources. As Branch Chief I manage all aspects of research at the CAFRL including how the design of fishways affects the ability of migratory fish to move around dams and under road crossings, the physiological processes that allow fish to move between freshwater and saltwater, tracking and predicting the movement of fish in response to changes in stream temperature and flow rates, and work with endangered fish species.
