Research Interests

Calcium and potassium channels on the surface membrane of vascular muscle cells control calcium influx and potassium efflux, respectively, and thereby regulate arterial diameters. My research interests are 1) using ion channel genes as therapeutic agents to normalize blood pressure, and 2) understanding molecular mechanisms that regulate traffic and expression of ion channels in vascular muscle cells during hypertension and related conditions. We use a wide range of techniques including molecular biology, biochemistry, viral gene transduction, patch clamp, vessel perfusion, confocal and super-resolution imaging, and in vivo microscopy.
