Description of Research Expertise:
My role as an advanced heart failure clinician-scientist and director of the mechanical assist device program at Penn is to provide expertise in the area of myocardial failure in the more advanced stage of this syndrome. More recently I have been working on the emerging interface of metabolism and heart failure. The current focus of my research is the investigation of myocardial and systemic metabolism in the syndrome of chronic heart failure. Specifically, myocardial and systemic insulin resistance is being increasingly targeted as a mechanism of disease progression in chronic heart failure and the objectives as a translational researcher within my group have been to: 1. Understand the role of lipid and adipocytokine biology (leptin, adiponectin, resistin) in the emerging metabolic phenotype of heart failure; 2. Identify specific targets for improving myocardial energetics and whole-body metabolism in cardiomyopathic failure; and 3. Test the safety and efficacy through carefully designed pilot studies of “reversing” specific metabolic pathways which have been dysregulated in human heart failure. My collaborative network for this research currently includes the laboratories of Dr. Tim McGraw, Dr. Richard Shannon, Dr. Ken Margulies and Dr. Tom Cappola within my own group at Penn as well as the laboratory of Dr. Christian Schulze and Professor Ira Goldberg at Columbia University.
