My primary teaching responsibilities are directing our Cardiovascular-Renal-Pulmonary course for our second-year D.O. students. In addition to administrating the course, I also teach cardiovascular physiology and some cardiovascular pharmacology as well. In our Biomedical Sciences Program I also co-direct a graduate course, Vascular Control Mechanisms, and chair the Curriculum Committee. In addition to these cardiovascular-related courses, I also teach basic reproductive endocrinology to second-year D.O. students, and cellular biophysics/neurophysiology to first-year D.O. students.

My research centers upon applying cellular/molecular electrophysiological techniques to investigate cell excitability and signal transduction, especially in coronary arteries. Our main focus has been on understanding how gonadal hormones (e.g., estrogen, testosterone) modulate potassium channel activity in coronary artery smooth muscle cells to produce vasodilation. My current M.S. student is doing research to understand how modulation of potassium currents in astrocytes may protect against Alzheimer’s disease.
