 Profile

Eric Muth is a Professor of Psychology and has been on the Clemson University faculty since 2000. Before coming to Clemson, he served as an Aerospace Experimental Psychologist in the US Navy. He holds a bachelor of arts degree in psychology from Hartwick College, and master of science and doctoral degrees in psychology from the Pennsylvania State University. He served as the Director of the Institute for Human Factors and Ergonomics Research at Clemson from 2009-2016. During 2008-2009, he was a Humboldt Research Fellow in the Department of Psychosomatic Medicine and Psychotherapy Universität Tübingen, Tübingen Germany. His current research focuses on two main areas: developing wearable mobile health technologies for studying and changing eating behavior; and understanding the physiology and prevention of motion sickness, with particular emphasis on head-mounted displays. Eric has served as a graduate mentor throughout his career, has over 80 publications and has received funding from a variety of agencies including the Defense Advanced Projects Agency, the Office of Naval Research, the National Institutes of Health and several private corporations.

 Research Interests

• Developing wearable mobile health technologies for studying and changing eating behavior
