Dr Richard L. Summers is a Professor of Emergency Medicine and Physiology and Biophysics at the University of Mississippi Medical School, where he serves as the Associate Vice Chancellor for Research. His research career has focused on translating basic science concepts into practical biomedical applications and interpreting clinical experiences in the context of fundamental physiologic meaning. Through training received under the eminent Arthur C. Guyton, his work has been facilitated by the use of advanced dynamic and integrative computer models of human physiology. With this modeling and systems analysis methodology, he has been able to pinpoint the critical functional mechanisms responsible for complex pathophysiologic conditions and received the Resuscitation Science Award from the American Heart Association for work in the development of a computer model platform designed to study hemodynamic states. He previously served for more than a decade as the Scientific Lead for the NASA Digital Astronaut Project to advance the understanding of the biologic adaptations of humans to microgravity conditions.
