Saurabh S. Thosar, Ph.D., M.S., OTR/L

  • Assistant Professor, Oregon Institute of Occupational Health Sciences

Biography

Saurabh received a B.O.Th in Occupational Therapy from Maharashtra University of Health Science in India, an M.S. in Movement Sciences from the Univ. of Illinois Chicago, and a Ph.D. in Human Performance (Physiology) from Indiana Univ. Bloomington. He is a certified clinical exercise specialist and licensed occupational therapist. Saurabh joined Dr. Shea's group as a postdoctoral fellow in January 2014 and has received a fellowship from the National Space Biomedical Research Institute, an early clinical investigator award from the Medical Research Foundation of Oregon, and a postdoctoral fellowship from the National Institutes of Health. Dr. Thosar studies the interactions between sleep, circadian rhythms and physical inactivity/activity as they relate to cardiovascular disease; and the development of chronotherapeutic countermeasures to cardiovascular risks in vulnerable populations.
