Dr. J. Mikhail Kellawan received his BSc (Honors) from the University of Guelph (Guelph, Ontario, Canada) and his MSc from the University of Victoria (Victoria, British Columbia, Canada). He completed his doctoral work at Queen’s University (Kingston, Ontario, Canada) before completing a Postdoctoral Fellowship at the University of Wisconsin-Madison. Dr. Kellawan has exhibited excellent scholarly potential during his graduate and post-doctoral work which includes research awards from the American Heart Association, and several from the American Physiological Society. Currently, Dr. Kellawan is an Assistant Professor and the Director of the Human Circulation Research Laboratory (HCRL) in the HES department. His work largely focused on mechanisms that control blood flow in skeletal muscle and cerebral circulations during exercise and environmental stress in humans. His work is designed to understand the physiological mechanisms that limit cardiovascular support of the brain and skeletal muscle with the aim of developing treatments and strategies to improve human health and performance.
Dr. Kellawan is also a member of the Cellular & Behavioral Neurobiology Graduate Program (http://www.ou.edu/cbn/)
