Barbara Zehnbauer, PhD, FACMG

Dr. Zehnbauer is the medical director of the Molecular Diagnostic Laboratory at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis, MO. She is professor in the departments of Pathology and Immunology, and Pediatrics.  Barb received her AB from Southern Illinois University and her SM and Ph.D. from the University of Chicago. Her postdoctoral training included fellowships in viral oncology (University of Wisconsin with Fred Blattner) and in oncology (Johns Hopkins Univ. School of Medicine with Bert Vogelstein).  Dr. Zehnbauer is a diplomate of the American Board of Medical Genetics with specialty certification in Clinical Molecular Genetics.  She is also the Director of the Molecular Core Laboratory of the Siteman Cancer Center, an NCI Comprehensive Cancer Center, at Washington University School of Medicine. 

Dr. Zehnbauer is a member of  the American Association for Cancer Research, American College of Medical Genetics, Academy of Clinical Laboratory Physicians and Scientists, American Association for Clinical Chemistry, Society of Critical Care Medicine, and Association for Molecular Pathology (immediate past-president).  She also serves on the College of American Pathologists (CAP) Biochemical and Molecular Genetics Resource Committee which supervises laboratory proficiency testing for inherited disease testing and pharmacogenetics.  As a member of the CAP Pharmacogenetics Working Group, she was instrumental in the development of the recent proficiency survey for pharmacogenetic testing (PGX) which was introduced in 2007.  Her primary research interests are development and validation of clinical molecular diagnostics in the characterization of pathogenic variation.  Dr. Zehnbauer’s clinical laboratory performs testing for inherited disorders, hematopathology, solid tumors, bone marrow engraftment monitoring and pharmacogenetics of cancer therapeutics.
