 Description of Research:

My current research focuses on understanding the mechanisms responsible for the decreased cardiac contractile force in patients with sepsis and septic shock (a clinical entity also known as sepsis-induced cardiomyopathy). Specifically, in the last few years I have been studying mechanisms of intracellular calcium homeostasis and nitric oxide (NO) signaling in the heart. NO appears to play a dual role in sepsis, having both pathologic and beneficial roles, and my goal is to be able to propose novel therapeutic agents that will specifically correct the former and potentiate the latter.

Previously, I have been interested in understanding the mechanisms of cardiac excitation contraction coupling (the process that links the cardiac action potential to the development of contractile force, and the main determinant of cardiac contractile force), during my graduate studies in Physiology at the University of Bristol, UK, which were followed by a research fellowship at Johns Hopkins University. At Johns Hopkins I studied how the process of excitation-contraction coupling is compromised in the failing heart, and devised novel therapeutic strategies.  My current interest in sepsis-induced cardiomyopathy is partly the result of my training and current work as a clinical anesthesiologist at Mass General Hospital.
