Ashley Margol, MD is originally from Jacksonville, Florida, where she and completed her undergraduate training at the University of Florida where she majored in zoology. She moved to Los Angeles to attend medical school at the Keck School of Medicine at the University of Southern California. She did her pediatric residency at Los Angeles County-University of Southern California after which she was honored to spend a fourth year as chief resident. Ashley recently completed her pediatric hematology-oncology fellowship at Children’s Hospital Los Angeles and is currently spending an additional year at Children’s Hospital Los Angeles training in pediatric neuro-oncology. Her research is examining the presence and role of inflammation in pediatric medulloblastoma, and she will complete her Masters of Science in Clinical, Biomedical and Translational Research this fall.
