Dr. George Daley, dean of Harvard Medical School and the Caroline Shields Walker Professor of Medicine at HMS, is an internationally recognized leader in stem cell science and cancer biology. He is also a longtime member of the HMS faculty whose work spans the fields of basic science and clinical medicine. Dr. Daley has been professor of biological chemistry and molecular pharmacology at HMS since 2010 and was an investigator of the Howard Hughes Medical Institute until assuming the Deanship. He previously held, as its inaugural incumbent, the Samuel E. Lux, IV Chair in Hematology/Oncology at Boston Children’s Hospital and was the Robert A. Stranahan Professor of Pediatrics and Professor of Biological Chemistry and Molecular Pharmacology at HMS.

A former chief resident in medicine at Massachusetts General Hospital, Dr. Daley maintained an active clinical practice in hematology/oncology at Mass General and then at Boston Children’s, until assuming his administrative role as director of the Pediatric Stem Cell Transplantation Program at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. He has served since 1995 as a member of the faculty of the Harvard-MIT Division of Health Sciences and Technology (HST), since 2004 as a founding member of the executive committee of the Harvard Stem Cell Institute, and since 2009 as an associate member of the Broad Institute of MIT and Harvard.

Dr. Daley’s research focuses on the use of mouse and human disease models to identify mechanisms that underlie blood disorders and cancer. His lab aims to define fundamental principles of how stem cells contribute to tissue regeneration and repair, and improve drug and transplantation therapies for patients with malignant and genetic bone marrow disease. Dr. Daley received his MD from Harvard Medical School, graduating in 1991 with the rare distinction of summa cum laude.
