Muscle, Movement, and Biophysics

Muscle, Movement, and Biophysics

The study of fundamental muscle cell physiology, and how muscles function together to allow action, from contraction of the heart to movement of limbs. Particular research strengths are on understanding the fundamental biophysics of molecular, cellular, and whole-muscle interactions, using quantitative methods to describe the behavior of single molecules as well as movement and posture of humans.
