Brian Hafner is the project manager and Senior Bioengineer for engineering-related research at PRS, including the Transtibial Alignment System (TTAS), the Advanced Biomimetic Lower Extremity (ABLE) prosthetic ankle, and the Amputation Surgical Education projects. Brian also manages PRS's technical resources including the gait laboratory, computer systems,
and biomechanics laboratory.

Brian graduated with a Ph.D. in Bioengineering in
March, 2003 from the University of Washington. His dissertation, entitled “ Transtibial amputee gait adaptation: correlating residual limb compliance to energy storage and return prosthetic foot compliance in bouncing gait,” examined the complex interaction between the prosthetic and residual limb in bouncing gaits such as jogging and hopping. His research interests include amputee gait analysis, lower-limb prosthetic alignment methodologies, and multimedia-based education focusing on amputation surgery and prosthetic care.

Brian received a Bachelor of Science degree in Mechanical Engineering from Oklahoma State University in 1996. Before graduating, Brian worked as an engineering intern with Pratt & Whitney/United Technologies in the Commercial Electronic Engine Control Systems Division.
