L. Gabriel Navar

Originally from El Paso, Texas and a graduate of Texas A&M University, Luis Gabriel Navar “Gabby” received his Ph.D. in 1966 from the University of Mississippi under the direction of Dr. Arthur Guyton. He served on the faculties of the University of Mississippi and the University of Alabama at Birmingham. In 1988 he joined Tulane University serving as Professor and Chair of the Department of Physiology and Director of the Center for Biomedical Research Excellence in Hypertension and Renal Biology.

Dr. Navar’s research focuses on hormonal and paracrine mechanisms regulating renal hemodynamics, glomerular filtration rate, and sodium excretion and how these are altered in angiotensin II dependent hypertension. His work also provided significant insights into the role of angiotensin (Ang) II in regulating renal hemodynamics, tubular sodium absorption and modulating the sensitivity of the macula densa feedback mechanism. His group demonstrated that changes in intrarenal production of nitric oxide in response to changes in arterial blood pressure alter sodium reabsorption and underlie the phenomenon of pressure natriuresis. Dr. Navar’s group demonstrated the importance of the intrarenal and intratubular generation of Ang II and angiotensinogen in Ang II-dependent hypertension and diabetes mellitus.

Dr. Navar has had leadership roles serving as Councilor and President of the American Physiological Society (APS) (1998-99) and President of the Association of Chairs of Departments of Physiology (1996-97). Dr. Navar is an active member of many societies including the American Physiological Society, ASN, AHA, and ASH.  He has served on study sections (NIH, VA, AHA) and on Editorial Boards for various journals including American Journal of Physiology and Hypertension.

Dr. Navar has received numerous awards including the Gottschalk Award, the Bodil Schmidt-Nielsen Distinguished Mentor and Scientist Award, the Berliner Award and the Walter B. Cannon Award from APS, the Richard Bright Award from ASH, and the Dahl award, the Corcoran Award and the Excellence in Hypertension Research award from the Council for High Blood Pressure Research of the AHA.
