Ruth Tatevossian, MD, PhD

  • Director, Diagnostic Biomarkers Shared Resource



MB, BS – King’s College School of Medicine, University of London
PhD - University College London

Professional Experience

Dr. Tatevossian trained as a pediatric oncologist in the United Kingdom, and completed her PhD studying the molecular genetics of pediatric low-grade glioma. She joined the Pathology department at St. Jude in 2010 to work in the field of translational medicine, utilizing research discoveries from brain and solid tumors to develop molecular biomarkers for the clinical service. Dr. Tatevossian supervises correlative studies supporting clinical trials as Director of the Diagnostic Biomarkers Shared Resource. She is also the Technical Director for Neuropathology and Solid Tumor Pathology.
