Research Focus

My research program is primarily concerned with elucidating mechanisms associated with the regulation of salt and water balance in aquatic animals. In this regard we place an emphasis on the endocrine system as a link between environmental change and physiological response as well as the permeability properties of occluding junctions – vertebrate tight junctions and invertebrate septate junctions.

We use model organisms that allow broad insight into the physiological and biochemical processes under study, such as aquatic arthropods, an extant agnathan (the sea lamprey), teleost fishes and amphibia. Current areas of interest include (but are not limited to) the regulation of epithelial permeability in response to environmental and systemic change, endocrine factors that regulate paracellular permeability, and the exposition and characterization of occluding junction proteins in ionoregulatory epithelia.

My goals are to gain a broader understanding of how animals "work" and to run a research program where the intellectual involvement and capacity for growth and development of trainees is front and center.
