My work focuses on the physiology and biophysics of skeletal muscle. The work focuses primarily on probing the interactions of actin and myosin and the role of the passive resistance provided by titin protein filaments. I am interested in the relationship between macromolecular structures and their physiological functions. I the intricate organization and interaction of macromolecules in skeletal muscles and in the eye provide model systems for the study of the coupling of form and function. It is our hope that this combination of mechanical and biochemical data will help us to relate better molecular level information to the physiological responses to biological tissues.
