Cardiovascular Medicine

About

Bruce D. Johnson, Ph.D. is a professor of medicine and physiology and a consultant in the Department of Cardiovascular Medicine. He has joint appointments in the Division of Preventive, Occupational and Aerospace Medicine and in the Department of Physiology and Biomedical Engineering. He is the director of the Mayo Clinical Research Unit's Energy Balance Core Laboratory and directs his own research laboratory in human integrative and environmental physiology. The majority of his research has focused on factors limiting human performance in various clinical syndromes, in athletes and under extreme environmental conditions. He has led field studies in Antarctica, funded through the National Science Foundation, and on Mount Aconcagua in Argentina, Mount Everest and Mount Kilimanjaro and studied unique populations such as breath-hold divers in Croatia and F-22 pilots from the U.S. Air Force. His clinical research focuses on novel methods for detection and tracking of chronic disease as well as environmental factors that may be involved in disease risk. His laboratory also works closely with consumer and medical device companies that track health status through wearable or passive sensing as well as with early-phase supplement and pharmaceutical company products. His work has been funded by the NIH, DOD, NSF, state of Minnesota and industry.
