My research concerns the role that genes play in physiological processes. The particular processes I study include the systems fish employ to control osmoregulation, and in particular, ion and water transport in fish. My research encompasses mostly molecular biological/physiological approaches and I have mainly specialized in research on euryhaline teleost fish such as eels (Anguilla sp.) and recently also killifish (Fundulus heteroclitus). I additionally carry out similar work on Elasmobranchs such as the Dogfish (Squalus acanthias).
