Leonard I. Zon, M.D., is the Grousbeck Professor of Pediatric Medicine at Harvard Medical School, Investigator at Howard Hughes Medical Institute,[1] and Director of the Stem Cell Program, Children’s Hospital Boston.[2]
He received a B.S. degree in chemistry and natural sciences from Muhlenberg College and an M.D. degree from Jefferson Medical College. He subsequently did an internal medicine residency at New England Deaconess Hospital and a fellowship in medical oncology at Dana-Farber Cancer Institute. His postdoctoral research was in the laboratory of Stuart Orkin.[3]
Dr. Leonard Zon is internationally recognized for his pioneering work in the fields of stem cell biology and cancer genetics. He is founder and former president of the International Society for Stem Cell Research[4] and chair of the Executive Committee of the newly formed Harvard Stem Cell Institute (HSCI).[5] He recently completed a term as President of the American Society for Clinical Investigation.[6] In 2005, Dr. Zon was elected to the Institute of Medicine of the National Academies.[7] In 2008, Dr. Zon was elected to the American Academy of Arts & Sciences.[6]
Dr. Zon's laboratory uses the zebrafish as a model system for understanding vertebrate blood development. Zebrafish blood formation is similar to that of humans, and several mutants have disorders resembling human disease. It is possible to evaluate in the zebrafish genetic pathways important for vertebrate hematopoiesis. Dr. Zon also uses the zebrafish to study cancer.[2]
