Li Han received a B.S. and an M.S. in Biomedical Engineering from Xi'an Jiaotong University in 1989 and 1992 respectively, and a Ph.D. in Computer Science from Texas A&M University in 2000. She was a postdoc fellow at Carnegie Mellon University from 2000 to 2002. She has been with Clark since 2002.

Current Research and Teaching

Professor Han's main research interests are in robotics and computational protein folding. Her recent work focuses on the computational study and mathematical analysis of configuration spaces and motions of multibody systems such as robots and proteins. Professor Han enjoys teaching a wide variety of courses. She is the faculty advisor of Clark Competitive Computing Club (C4) and the coach of Clark programming contest teams.
