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 national and international news organizations that include the British Broadcasting Corporation, the Public Broadcasting System, National Public Radio, the New York Times, and the Wall Street Journal as well as popular press outlets such as ESPN, Sports Illustrated and the Wired Magazine.

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 international projects. These include the "Michael Johnson, Wired Athlete" project prior to the Sydney Olympics, the “Physics of Basketball Flopping” project examining the mechanics of basketball collisions, and investigations into the mechanics of sprinting and jumping on artificial limbs on behalf of World Athletics and the International Court of Arbitration for Sport in Switzerland.
