    Jeffrey Robbins, PhD Director and Endowed Chair, Molecular Cardiovascular Biology

    established the means to direct the heart to synthesize normal and mutant proteins. They can turn these on and off at will and this allows them to establish cause-and-effect relationships between mutant proteins and the development of cardiac disease. The lab is particularly interested in how protein aggregation can cause cardiac disease but also studies the contractile protein mutations that cause hypertrophic cardiomyopathy and heart failure.
