Dr. Richard Neptune earned his Ph.D. in Mechanical Engineering from the University of California, Davis in 1996 and has served on the Department of Mechanical Engineering faculty at UT Austin since 2001 in the Biomechanical Engineering and Dynamic Systems & Control programs. His research integrates musculoskeletal modeling, computer simulation and experimental analyses to identify the neuromotor and biomechanical mechanisms that contribute to locomotor impairments in those with movement disabilities including lower-limb amputees, stroke patients and wheelchair users. He is also involved in research aimed at improving the performance of orthotic and prosthetic devices using advanced additive manufacturing techniques. His research has been supported primarily by the Department of Veteran’s Affairs, National Science Foundation and National Institutes of Health. He has received the American Society of Biomechanics Young Scientist Award and CAREER award from the National Science Foundation. He is also the recipient of the Da Vinci Award from the Engineering Society of Detroit and National Multiple Sclerosis Society for the application of Selective Laser Sintering techniques to improve mobility for those with lower-limb disabilities. In 2006, he received the Outstanding Young Scientist Award from the Houston Society for Engineering in Medicine and Biology. In 2012 he was named a Professor of Excellence by The University of Texas at Austin and in 2013 he received the Joe and Bettie Branson Ward Endowed Excellence Award from The University of Texas at Austin for his teaching and research that has contributed to changes of positive value to society. In 2015 he received the Lockheed Martin Aeronautics Company Award for Excellence in Engineering Teaching and in 2016 he was elected Fellow of the American Society of Biomechanics. He is currently a Provost Teaching Fellow, holds the John T. MacGuire Professorship in Mechanical Engineering, and the Department Chair.
