Current Research

Evaluating the pathogenesis of heart failure associated with diabetes; assessing the cellular consequences of elevated sugar and fats on isolated heart muscle cells, primarily focusing on excitation-contraction coupling and insulin signaling; studying interventions which can prevent or reverse heart disease associated with diabetes.

Research Interests

cellular mechanisms contributing to development of diabetic cardiomyopathy
