Biography

Anton E. Bowden loves BYU and especially his interactions with the students in the Mechanical Engineering Department!  His background and research interests are in spinal biomechanics, medical device design, computational biomechanics, and engineering leadership education.  He directs the BYU Applied Biomechanics Engineering Laboratory.  He received his PhD in Bioengineering from University of Utah and his BS in Mechanical Engineering from Utah State University.  He is a licensed professional engineer and a recipient of a National Science Foundation CAREER Award.  He is grateful to have been awarded the Weidman Professorship in Leadership and enjoys serving in various committee capacities for the Orthopaedic Research Society.  He speaks Spanish with moderate fluency and is currently trying to learn Mandarin Chinese.  He and his wife Jennifer love learning and traveling with their children and live in Lindon, Utah.

Research

Dr. Bowden's primary research interests are in spinal biomechanics and medical device design, with an emphasis on developing an improved understanding of the mechanical triggers for low back pain. He uses non-linear finite element analysis, medical imaging, and mechanical testing to characterize the responses of biological soft tissues.

He has a strong educational focus on developing engineering leaders who will recognize and act on opportunities to make the world a better place.
