Dr. Errol Lobo is an Assistant Professor of Anesthesia at UCSF. He received his undergraduate education at the University of San Francisco and his Doctorate in Medicine at the University of California San Francisco School of Medicine. Dr. Lobo also holds a Doctorate in Philosophy from the University of California San Francisco. Dr. Lobo is a former University of California President's Fellow and Robert Wood Johnson Foundation Fellow. Dr. Lobo's anesthesia practice is focused primarily on obstetrical anesthesia and on anesthesia for vascular surgery.
Dr. Lobo's research interests include the regulation of calcium signaling pathways in cells stimulated by proteins that cause blood vessels to constrict. The protein he is primarily interested in is endothelin. Endothelin is thought to play a role in the pathogenesis of hypertension. In the fetus, endothelin is intimately involved in renal development.
Luis Gabriel Navar received his Ph.D. in 1966 at the University of Mississippi under the direction of Dr. Arthur Guyton. He served on the faculty of the University of Mississippi and the University of Alabama at Birmingham before joining Tulane in 1988. He is Director of the Center for Biomedical Research Excellence in Hypertension and Renal Biology and Professor and Chair of the Department of Physiology. Dr. Navar has concentrated his research on the hormonal and paracrine mechanisms that regulate renal hemodynamics, glomerular filtration rate, and sodium reabsorption, and their relationships to the pathophysiology of hypertension and diabetes. His work has been recognized and lauded by his peers, as evidenced by numerous awards. Dr. Navar has had leadership roles serving as Councilor and President in the American Physiological Society (APS) and President of the Association of Chairs of Departments of Physiology and was Chair of the Council for High Blood Pressure. Dr. Navar has also been President of the Interamerican Society of Hypertension. He served on the Council of Academic Societies of the AAMC as well as on numerous peer review groups and study sections for the NIH, the VA, and the AHA. He has also served as Associate Editor for the American Journal of Physiology and Hypertension.
Research programs in Dr. Navar's laboratory investigate hormonal and paracrine mechanisms regulating renal hemodynamics, glomerular filtration rate (GFR), and sodium excretion. Intense activity is also focused on the pathophysiology of hypertension and the role of the intrarenal renin angiotensin system (RAS) in altering kidney function to lead to in angiotensin II dependent hypertension.
