Research Interests

Many animals are adapted to survive large changes to their surroundings (e.g., tidal, diurnal, and seasonal changes, or changes as a result migration between two different environments). As an environmental physiologist, I am interested in understanding how animals acclimate to these changes. In my research, I use euryhaline fish (fish that tolerate large fluctuations in environmental salinity) to study the organismal, cellular, and molecular mechanisms of salinity acclimation. I am particularly interested in researching endocrine regulation of salinity acclimation and how other environmental stressors (e.g., temperature, hypoxia, PCO2) affect salinity acclimation in some of the most primitive euryhaline fishes.
