Research Interests
Calcium and potassium channels conduct Ca2+ and K+ ions, respectively, across the surface membrane of vascular muscle cells. Abnormalities in these channels trigger contraction of small arteries resulting in high blood pressure (hypertension). The goal of our laboratory is to discover abnormalities of ion channel expression and composition that contribute to systemic and pulmonary hypertension, and identify channel-based therapies to treat these diseases. We employ a multi-faceted approach of patch-clamp, molecular, cellular and in-vivo techniques to accomplish this goal.
