Dongjun Lee, an assistant professor in the Department of Mechanical, Aerospace and Biomedical Engineering, recently received a National Science Foundation CAREER Award for his research. Lee is developing algorithms and theories that allow people in different locations to interact and collaborate with in the cyberspace using virtual reality force or haptic feedback. These results will lay the foundations for such applications as virtual collaborative surgical training and sculpting, networked computer games with inter-user force feedback, and virtual evaluation of engineering products.
Lee earned his Ph.D. in mechanical engineering at the University of Minnesota and spent two years as a postdoctoral fellow at the University of Illinois before joining the faculty of the University of Tennessee in 2006.
