Structure-function (biomechanics) of the musculoskeletal system and how animals are specialized for diverse locomotor behaviors including walking, running, digging and climbing. Research in my laboratory is currently focused on three areas: (1) the influence of muscle contractile function on limb bone loading during terrestrial locomotion, (2) muscle architectural properties in the forelimbs of digging specialists, and (3) myosin heavy chain isoforms and muscle fiber types in the prehensile tails of climbing animals.
