Contrast echocardiography and new ultrasound imaging technology for the non-invasive assessment of ventricular blood pool, myocardial perfusion, and coronary vascular anatomy and physiology

I have numerous research projects involving the assessment of contrast echocardiography to detect myocardial perfusion using new ultrasound imaging modalities.

Cardiovascular response to microgravity and adaptation during space flight

I have collaborated with NASA scientists to study the acute and chronic physiological adaptations of the cardiovascular system to weightlessness in space, and develop countermeasures to orthostatic intolerance induced by microgravity.

Women and Heart Disease I am interested in the evaluation, primary and secondary prevention, risk stratification by noninvasive testing, and treatment of women with heart disease
