Research Interests
I have extensive research experience in cardiovascular physiology and I maintain a strong interest in regulation of vasomotor activity by ion channels expressed by arterial smooth muscle cells. I'm also interested in how factors produced by the vascular endothelium influence blood vessel function. I use a number of experimental approaches for these studies, including patch clamp and intracellular electrophysiology, molecular biology, antisense-mediated suppression of ion channel expression in intact arteries, high-speed laser scanning confocal imaging of dynamic intracellular Ca2+ events, and video microscopy recordings of changes diameter and smooth muscle cell Ca2+ in pressurized resistance arteries. My research focuses on the role of transient receptor potential (TRP) channels expressed by cerebral artery smooth muscle in vascular function. TRP channels are a ubiquitously expressed superfamily of cation channels that are important in sensory transduction, osmotic regulation, and other physiological and pathophysiological responses.
