Dr. Henny Billett has been Chief of the Division of Hematology since 2012 and Professor of Clinical Medicine and Pathology since 2002.

Dr. Billett's clinical research interests are in risk factors for thrombosis and microvascular disease, with emphasis on epidemiological aspects and outcomes research. Her investigations focus on the effect of race and ethnicity on thrombosis in general and, in particular, the thrombotic and microvascular complications of sickle cell disease.

Recent investigations have focused on:

1. Hemolysis patterns in CF-LVAD patients and their association with device thrombosis (collaboration with Dr. Ulrich Jorde, Cardiology)
2. Evaluation of CNS function and cognition in patients with sickle cell disease (collaboration with Dr. Craig Branch, Gruss Magnetic Resonance Research Center)
3. Priapism in murine and human models of sickle cell (collaboration with Dr. Kelvin Davies)
4. Multicenter studies
   • P-Selectin therapy in sickle cell disease
   • Viral co-infections, paraproteinemia and thrombosis

Dr. Billett completed an undergraduate degree from the University of Pennsylvania cum laude; medical school Mount Sinai School of Medicine; and an MSc from the London School of Hygiene and Tropical Medicine in London. She was a Senior House Officer at St. Bartholomew's Hospital, London, and completed her training at Montefiore.
