- Human coronary microvascular dysfunction
- The role of sphingolipids in vascular function
- Mechanisms and treatments of vasoplegia
- Surgical prehabilitation in frail patients
Dr. Freed’s research primarily focuses on the role that sphingolipids have in the development of endothelial dysfunction in the human microcirculation. Elevated plasma levels of ceramide, a prototypical sphingolipid, is now considered an independent risk factor for major adverse cardiovascular events in otherwise healthy people. The Freed lab is currently investigating how these bioactive lipids are regulated in human endothelial cells.
As a cardiac anesthesiologist, Dr. Freed is also interested in intraoperative blood pressure control including mechanisms and treatments of vasoplegia. Other interests include translating her work in the lab to improve outcomes for surgical patients.
