We are interested in the molecular mechanisms of signal transduction, particularly in muscle contraction and cardiovascular disease. The two main research areas in my laboratory are: the role of the proteasome in normal, protected and diseased cardiac and skeletal muscle and the role of troponin in calcium regulation of muscle contraction in hypertrophic, dilated and restrictive cardiomyopathies.
