Research Interests – Skeletal Muscle Structure and Function

My research focus is on the cellular and molecular organization of skeletal muscles and how these properties change in response to development, exercise, and other demands. The physiological properties of muscles are primarily derived from their cellular and molecular organization. All muscle work is based on muscle shortening, produced when myosin heavy chain (MHC) motors bind to actin filaments and pull them. Yet within this common design, great diversity exists with respect to cellular organization and function. I a­­­­m particularly interested in the organization of skeletal muscles from the standpoint of task-specific design, and the integration with organismal function. Muscles differ with respect to their specific assemblage of myofibrillar protein isoforms, including multiple isoforms of motor proteins (myosins) and of the regulatory proteins (tropomyosin and troponins I, T, and C) that function to switch the muscle on and off. Structural features, such as sarcomere width, also represent design parameters that affect muscle function.  In my lab we work to understand how these various parameters are matched with one another to create a specific muscle phenotype.  We are currently studying single fibers co-expressing two or more MHC isoforms (hybrid fibers) and their role in mammalian muscle plasticity. We are also studying skeletal muscles in running ghost crabs, with the goal of understanding how these muscles power rapid running.
