Brett Colson, PhD

Assistant Professor, Cellular and Molecular Medicine
Research Interests: 

The research goal of my laboratory is to understand the molecular motions and interactions of proteins involved in regulating contractile function of healthy cardiac and skeletal muscle, to determine the culprits of contractile dysfunction and remodeling in muscle disorders and cardiovascular disease, and then apply these insights to design novel therapies. We use biophysical approaches, such as time-resolved spectroscopy with site-directed probes to assess protein structural dynamics and mechanical measurements of isolated muscle fibers to assess contractile force and kinetics, in order to establish structure-function relationships inherent to the molecular, biochemical, and physiological mechanisms.
