Renal physiology; the role of sensory receptors in regulating renal function; identifying renal olfactory receptor ligands and relating them to whole-animal physiology.

Our lab is interested in the role that chemosensation plays in regulating physiological processes, particularly in the kidney and the cardiovascular system. We have found that sensory receptors (olfactory receptors, taste receptors, and other G-protein coupled receptors) are expressed in the kidney and in blood vessels, and that individual receptors play functional roles in whole-animal physiology.  We are currently working to identify the full complement of sensory receptors found in the kidney, and are working to understand the role that each receptor plays in whole-animal physiology by using a variety of in vitro (receptor localization, ligand screening) and in vivo (whole-animal physiology) techniques.
