Overview

  • Dr. Pollock earned his Ph.D. degree in Physiology from the University of Cincinnati in 1983. He completed a post-doctoral fellowship at the University of North Carolina at Chapel Hill. He then spent two years as a Senior Scientist at the Institute for Circadian Physiology at Harvard University in Boston before taking a position in the Drug Discovery division of Abbott Laboratories in Chicago. In 1995, he accepted a faculty position in Vascular Biology Center at the Medical College of Georgia (now known as Augusta University) where he rose to the rank of Regents’ Professor. In 2010, he became the founding chief of the Section of Experimental Medicine in the Department of Medicine. In 2014, Dr. Pollock moved to UAB where he serves as Director of the Cardio-Renal Physiology and Medicine section in the UAB Department of Medicine whose charge it is to develop translational research and training programs. In 2016, he was named the James A Schafer NRTC Endowed Professor of Medicine.

    In 2015-2016, Dr. Pollock served as the 87th President of the American Physiological Society. Dr. Pollock is a fellow of the American Heart Association, the American Society of Nephrology and the American Physiological Society. He has served as Associate Editor for several journals including American Journal of Physiology: Regulatory, Integrative and Comparative Physiology and the Journal of the American Heart Association and is now serving as Editor-in-Chief of Comprehensive Physiology. He is also a founding member of the International Advisory Board on Endothelin who organize the bi-annual International Conferences on Endothelin. Dr. Pollock has also served on numerous NIH and AHA grant review committees. Dr. Pollock has also served as scientific advisor for several companies in the clinical development of endothelin antagonists including Speedel Pharmaceuticals, Abbott Laboratories, Pfizer Corporation, and Gilead Pharmaceuticals.

    Research Overview

  • For over 30 years, Dr. Pollock has conducted research on the renal mechanisms contributing to blood pressure regulation and renal disease. Dr. Pollock's lab has a wide range of expertise that includes chronic assessment of blood pressure (telemetry), hemodynamics, and renal function in rodent models of hypertension, diabetes, acute kidney injury, and chronic kidney disease. Dr. Pollock has provided considerable evidence through the years that the renal endothelin system is an important physiological regulator of sodium excretion and contributes to salt-dependent hypertension. He is currently Program Director of an NHLBI-funded Program Project Grant on the renal control of sodium excretion with a focus on renal autocrine and paracrine factors. His work specifically has begun to explore circadian control of renal function. Additional research interests include a long-standing collaboration with Dr. Jennifer Pollock in the area of stress in cardiovascular risk. More recently, he has several funded projects related to efforts to understand mechanisms responsible for sickle cell nephropathy.
