I attended the University of Illinois at Urbana-Champaign, graduating with a B.S. in Electrical Engineering. I then went to Stanford University to do a Ph.D. in the Mechanical Engineering Dept.'s Design Division. There, I worked with Dennis Carter studying orthopaedic biomechanics and morphology of trabecular bone. I then worked with Felix Zajac for my Ph.D., studying ways to describe the set of possible accelerations and forces that can be produced in a multi-body mechanical system, and applied that to analyzing human balance. I received my Ph.D. and then went to the R.S. Dow Neurological Sciences Institute in Portland, Oregon, to work with the Center for Vestibular Research, which was established to encourage interdisciplinary research involving neurophysiologists and engineers. I then came to the University of Michigan, where I am now an Associate Professor of Mechanical Engineering. My teaching is in the areas of dynamics & vibrations, and systems & control. I retain my research interests in human balance control, relying on the methods of control theory and multi-body dynamics. I have a variety of other interests described in my Research page.
