Margaret H. Baron, MD PhD, is Fishberg Professor of Medicine;  Senior Associate Dean for Education and Director of the MD-PhD Program;  Director, Program in Hematology and Blood Disorders (Division of Hematology and Medical Oncology);  and a member of the Tisch Cancer Institute (TCI)and Black Family Stem Cell Institute (BFSCI).  She is also Program Director of an NIH-funded T32 Research Training Program in Molecular and Cellular Hematology (which can support postdoc and clinical fellows).  Dr. Baron is an established scientist who has over 25 years of continuous, independent NIH-sponsored research funding in hematopoiesis and a publication record spanning protein biochemistry, virology, cell biology, developmental biology, and stem cell biology. She is known for her work on the plasticity of the differentiated state, globin gene regulation, and developmental hematopoiesis.


Dr. Baron is a graduate of the Harvard-M.I.T. Program in Health Sciences and Technology (H.S.T.) and holds degrees from Harvard (A.B.), Harvard Medical School (M.D.) and M.I.T. (Ph.D.).  She trained in the laboratories of David Baltimore (Ph.D. thesis) and Tom Maniatis (postdoc).  Her first independent faculty position was in The Biological Laboratories at Harvard University, where she was an assistant and then associate professor before moving to a tenured position at Mount Sinai in 1997.  She served for 18 months (2006-2007) as Interim Co-Director of the BFSCI. 


Dr. Baron is a dedicated educator, having developed and directed courses for undergraduates, PhD and MD/PhD students at Harvard and Mount Sinai.  She is co-founder and former co-Director for the Developmental and Stem Cell Biology (DSCB) Multidisciplinary Training Area (MTA) for PhD and MD/PhD students.  She is a member of the Steering Committee for the Graduate School of Biomedical Sciences and served as Assistant Director of the Medical Scientists Training Program (MSTP) and as Co-Director for the former Mechanisms of Disease and Therapies Multidisciplinary Training Area (MTA).
