Raul Longoria


General Motors Foundation Centennial Teaching Fellowship in Mechanical Engineering

Department Research Areas:
Robotics and Intelligent Mechanical Systems

Dr. Raul G. Longoria received the B.S.M.E. and Ph.D. in Mechanical Engineering from the University of Texas at Austin in 1985 and 1989, respectively. He joined the Walker Department of Mechanical Engineering at the University of Texas at Austin (UT-Austin) in 1991 and holds the rank of Professor. His teaching and research interests focus on development and application of multi-disciplinary dynamic system modeling, vehicle system dynamics and controls, electromechanical system modeling and simulation, and application of machine learning and AI for smart hand tools. Dr. Longoria is a registered Professional Engineer in the State of Texas, and a member of the ASME, IEEE, SAE, and ISTVS.
