CTSI Profile

Overview

Dr. Hallows is studying the metabolic control of kidney epithelial salt and water transport mechanisms with relevance to hypertension, acute kidney injury and chronic kidney disease. He is also studying the role of metabolic changes in autosomal dominant polycystic kidney disease and other kidney diseases at various levels.

After completing his undergraduate training at Brown University, Dr. Hallows earned his PhD and MD degrees from the University of Rochester. He then went on to complete residency in internal medicine and then a fellowship in nephrology at the Hospital of the University of Pennsylvania. After spending a year as an instructor at the University of Pennsylvania, Dr. Hallows moved to the University of Pittsburgh as an assistant professor, then associate professor of medicine, before moving to the Keck School of Medicine of USC in 2015.
