Gray Thomas

Assistant Professor, Mechanical Engineering

Gray Cortright Thomas, Ph.D. is an Assistant Professor at Texas A&M University in the Department of Mechanical Engineering. He studies direct human control of physically interactive robots through a combination of strength amplification control, human modeling and estimation, and high-bandwidth design. He earned his 2019 Ph.D. in Mechanical Engineering from the University of Texas at Austin, where he worked on the topics of multi-contact impedance control for humanoid robots, system identification for robust control, and series elastic actuation. Prior to his Ph.D., he earned his B.S. in Engineering:Robotics at Olin College of Engineering in 2012. He was the recipient of the NASA Space Technology Research Fellowship and Olin Full-Tuition Scholarship. Other research interests include force-feedback, series-elastic actuation, and robust control.
