Research Interests:
Heart failure is more than just a condition of the cardiovascular system with secondary manifestations involving numerous other organ systems. Specifically, respiratory manifestations(pulmonary remodeling, ventilatory dysfunction, diaphragmatic myopathy, etc.) contribute to the salient features of heart failure, dyspnea and exercise intolerance, and often exacerbate the preexisting cardiovascular dysfunction. Therefore, my goal is to understanding the cause(s) and mechanism(s) of respiratory dysfunction in heart failure and to develop novel therapeutic for clinical translation.

Specific Projects:
. Diaphragmatic atrophy and weakness in heart failure
. Prevention and regression of diaphragmatic myopathy in hypertension and heart failure
. Pulmonary remodeling and mechanisms of acute pulmonary edema/inflammation following myocardial infarction
. Pharmaceutical manipulation of ventilation

Thesis Topic:
Physiological and molecular mechanisms of respiratory dysfunction during hypertension and the progression to heart failure.
