Richard Neptune


William and Bettye Nowlin Chair in Engineering

Department Research Areas:
Biomechanical and Biomedicine Engineering

Dr. Richard R. Neptune earned his Ph.D. in Mechanical Engineering from the University of California, Davis and has served on the Walker Department of Mechanical Engineering faculty at UT Austin since 2001. His research seeks to improve the quality of life for individuals with movement disabilities by integrating musculoskeletal modeling, computer simulation and experimental analyses to identify the biomechanical and neuromotor mechanisms that contribute to locomotor impairments. His research also seeks to improve the performance of orthotic and prosthetic devices using design optimization and advanced additive manufacturing techniques. He has received a number of awards for his teaching and research including the CAREER award from the National Science Foundation, the Lockheed Martin Aeronautics Company Award for Excellence in Engineering Teaching, the Van C. Mow Medal from the American Society of Mechanical Engineers, and the Founders Award from the American Society of Biomechanics. He is a fellow of both the American Society of Biomechanics and the American Society of Mechanical Engineers. He currently holds the William and Bettye Nowlin Chair in Engineering.
