Research Abstract:

Neuronal and myocyte bioelectricity arises from the atomic interactions of ion channels. While the atoms and molecules that form channels interact at nanometer and nanosecond time-scales, heart beats and neuronal signals travel over centimeters and seconds. Bridging these time and length scales is a primary barrier to developing useful small molecules therapies. To gain a multiscale understanding, we use computational models that are based on data we collect with cutting-edge biophysics methods.
