Mark Geil

Department Chair    Professor    

Bachelor of Science in Mechanical Engineering (minor in Philosophy) from North Carolina State University, 1993
Doctor in Philosophy in Biomedical Engineering from the Ohio State University, 1997


Biomechanics, prosthetics and orthotics, pediatrics


Mark Geil has degrees in Mechanical Engineering from North Carolina State University and Biomedical Engineering from the Ohio State University, where he specialized in human locomotion biomechanics. In his first faculty position at Georgia Tech he was instrumental in the creation of the world’s first entry-level MS program in prosthetics and orthotics. He arrived at GSU in 2004 as Director of the Biomechanics Laboratory. In 2013 he was named the founding Executive Director of the Center for Pediatric Locomotion Sciences.

Geil is also the chair of the Department of Kinesiology and Health at the College of Education and Human Development.

Geil is a Fulbright Senior Specialist awardee and winner of the Research Award from the American Academy of Orthotists and Prosthetists.
