Current research centers on the physiology and evolutionary biology of salt and water balance in aquatic vertebrates. Specifically, laboratory projects explore the molecular physiology and evolution of the extracellular calcium-sensing receptor, endocrine mechanisms mediating adaptive changes in drinking and alimentary tract function, and the biophysics of epithelial ion transport in the fishes.
