I am currently a postdoc at UC Berkeley working in the Biomimetic Millisystems Lab.  I obtained my Ph.D. at UC Irvine under Dr. J. Michael McCarthy where I maintained this website.  My research interests include the kinematic design of linkages, millirobotic systems, solutions to high degree polynomial systems, and the design of mechanical devices for rehabilitation.
