Dr. George R. Buchanan is a Professor of Pediatrics at the University of Texas Southwestern Medical Center (UT Southwestern) in Dallas, Texas.  He received his medical degree from the University of Chicago in 1970, followed by pediatric residency at Children’s Memorial Hospital in Chicago and hematology-oncology fellowship at Children’s Hospital Boston, Dana Farber Cancer Institute, and Harvard Medical School.

Dr. Buchanan has been at UT Southwestern since 1977 actively involved in the diagnosis and management of children and adolescents with blood diseases. He had been a national leader in investigator-initiated and multicenter collaborative research in many areas of hematology, including sickle cell disease, other anemias, bleeding disorders, and childhood cancer. He has had keen interest in training and mentoring young physician researchers and developing new treatment approaches for children affected with blood disorders and cancer. 

Dr. Buchanan has served as President of the American Society of Pediatric Hematology-Oncology (ASPHO) and twice on the Executive Committee of the American Society of Hematology (ASH).  His national honors include the Distinguished Career Award from ASPHO, the Mentoring Award in Clinical Research from ASH, and the Arnold Gold Foundation Award for Humanism in Medicine from the American Association of Medical Colleges.
