Anna Stanhewicz

Anna Stanhewicz, PhD is an Assistant Professor of Health and Human Physiology and is the director of the Microvascular Physiology Lab at the University of Iowa. She earned her bachelors degree from the University of Rhode Island and completed her doctoral and post-doctoral training at Penn State University. Dr. Stanhewicz's research program utilizes in vivo measures of cutaneous microvascular function to study how microvessel function is altered in disease and how intervention strategies can target these alterations to slow, halt, or reverse cardiovascular disease progression.
