A graduate of University of Minnesota Medical School (1973), Dr. Hebbel subsequently trained in Internal Medicine at the University of Washington and in Hematology at the University of Minnesota. He is former Director of the NIH Hematology Training Grant and former Vice Chairman for Research of the Department of Medicine, where he is currently Regents Professor and Clark Professor of Medicine. Although now retired from clinical practice, his past clinical activities (1979-2003) included hematologic malignancy, marrow transplantation and benign hematology, with particular emphasis on sickle cell anemia. His laboratory research currently focuses upon the vascular pathobiology of sickle disease and upon genetic determinants of individual variability in endothelial cell function.

Research Summary/Interests

Dr. Hebbel's research interests include: the vascular pathobiology of sickle disease; use of blood outgrowth endothelial cells (BOEC) for biomedical applications; and the role of genetically determined differences in endothelial biology as a determinant of clinical phenotypic heterogeneity of vascular disease. Dr. Hebbel's lab is currently emphasizing, respectively, the molecular physiology of tissue factor expression by endothelial cells, utility of BOEC for gene therapy and device coating, and role of inherited endothelial cell differences underlying stroke risk.
