Dr. Peter Weyand is a biomechanist and physiologist who joined SMU's Department of Applied Physiology and Wellness in the Fall of 2008. Prior to coming to SMU, Dr. Weyand directed research efforts at Harvard University's Concord Field Station, a large animal facility specializing in terrestrial locomotion and the Locomotion Laboratory of Rice University. His research subjects have included antelope, emus, rodents and professional athletes with and without limb amputations.

Dr. Weyand's scholarly work focuses on mechanics, metabolism and performance at the whole body level. His work is well-known to academics, practitioners and professionals across a number of performance-based fields. Dr. Weyand's scholarship has often moved from experimental settings into contemporary practice as a result of his ability to identify the key determinants of performance and commitment to explaining them. His science-education efforts have occurred via a variety of media organizations ranging from prestigious outlets such as the British Broadcasting Corporation, the Public Broadcasting System, National Public Radio, the New York Times, and the Wall Street Journal to popular press outlets such as ESPN, Sports Illustrated and the Huffington Post.

Dr. Weyand's expertise on the mechanical basis of motion and performance have led to him serve as a lead investigator in a number of high-profile projects. These include the "Michael Johnson, Wired Athlete" project prior to the 2000 Olympics, the Oscar Pistorius project prior to an appeal hearing before the Court of Arbitration for Sport in Switzerland in 2008, and the “Physics of Basketball Flopping” project examining the mechanics of contact sport collisions. Dr. Weyand currently serves as the lead scientist for the biomechanics and bio-modeling portion of the Sub-2-Hour marathon project based in the United Kingdom with satellite operations in Kenya and Ethiopia.
