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) limb bone loading during terrestrial locomotion, (2) muscle architectural properties in the forelimbs of digging mammals, and (3) myosin heavy chain (MHC) isoforms and fiber types in the prehensile tails of didelphid marsupials (opossums).
To answer questions about how animals evolved specialized anatomy for specific behaviors we use a variety of animal models. Our present locomotor investigations involve armadillos (bone loading) and eastern cottontail rabbits (acceleration performance and muscle fiber architecture). To investigate prehensile tail muscle physiology we collaborate with researchers to work with several species of opossums in the neo-tropical rainforests of Costa Rica.
