My principal research interest is the study of locomotor energetics from the perspective of mechanical engineering. To do this, I utilize many tools, including finite element modeling, motion capture, Matlab and kinematic/kinetic analysis. My lab (Primate Evolutionary Biomechanics Lab) is equiped with analysis computers, a scanner, and a 3D printer; primate skeletons and radioagraphs are available. I use the motion capture capabilities of the Human Motion Analysis Laboratory of the Dept of Rehabilitative Medicine and I collaborate with researchers in the Departments of Orthopaedics and Sport Medicine, Rehabilitation Medicine and Mechanical and Civil Engineering. My research is, however, firmly grounded in modern evolutionary theory.
