Dr. Leon Bernal, MD

Chief of Hematology and Medical Oncology

Dr. Leon Bernal-Mizrachi, MD, is board-certified in medical oncology and internal medicine, he is a clinical member of the comprehensive care team treating leukemia patients at Grady. Dr. Bernal-Mizrachi began his research career at the Miller School of Medicine at the University of Miami with Dr. Yeon Ahn. During his fellowship at Washington University in St. Louis, MO, Dr. Bernal-Mizrachi continued on his search to define the role of inflammation and cancer. Under Dr. Lee Ratner’s mentorship, he identified a novel prosurvival mechanism of each NF-kB pathway, an inflammatory signal. These findings ignited his interest in these signals and their role in B cell development and cancer development. To take advantage of new technologies and explore new avenues in these pathways, Dr. Bernal-Mizrachi trained at Cold Spring Harbor in the integrative statistical analysis of genome-scale data. This knowledge set the foundation for the current research interest. In Colombia, South America, he was Co-Director of the City’s Diabetes Program as part of Cali’s City Public Health Service in 1998-1999.
