John Halliwill graduated with a B.S. degree in zoology from The Ohio State University in 1991. In 1995, he received his doctorate in physiology from the Medical College of Virginia. He subsequently trained as a post-doctoral fellow at the Mayo Clinic and Foundation, until his appointment to the clinic’s staff as an assistant professor of anesthesiology in 1999.
In 2002, Dr. Halliwill joined the University of Oregon’s Department of Human Physiology. His research relates to how the human cardiovascular and respiratory systems adapt and respond to exercise and other stresses encountered during everyday life. This research has two major focus areas. First, studies are aimed at understanding why blood pressure is lower after exercise (a phenomenon known as postexercise hypotension). Second, studies are trying to identify what hormonal, neural, or metabolic factors are responsible for changes in blood flow in various regions of the body during exposure to environmental and physical stresses, such as altitude (hypoxic stress) or changes in body position (gravitational stress). Both of these focus areas are related to issues of human health and disease. He co-directs the Exercise and Environmental Physiology Labs.
