Rebekah Dumm

Rebekah Dumm, PhD is an Assistant Professor in the Department of Pathology & Immunology at Washington University School of Medicine in St. Louis. She serves as Associate Program Director for the CPEP Medical and Public Health Microbiology Fellowship and Medical Director of Bacteriology, Antimicrobial Susceptibility Testing, and Molecular Syndromic Infectious Disease Diagnostics at Barnes Jewish Microbiology & Molecular Infectious Disease Laboratories.

Her educational background includes:

• BS from University of Delaware
• PhD from Duke University
• CPEP Fellowship from University of Pennsylvania-Children’s Hospital of Philadelphia

Dr. Dumm's research centers on optimizing clinical microbiology diagnostics through evidence-based evaluation of emerging technologies. She specializes in establishing clinical utility for complex diagnostic systems, with primary focus on molecular pathogen detection, antimicrobial resistance profiling, and laboratory automation to enhance diagnostic accuracy and workflow efficiency. Her work directly addresses critical challenges in infectious disease management and antimicrobial stewardship.

Her publication portfolio demonstrates consistent contributions to diagnostic stewardship frameworks, molecular testing implementation, and real-world impact assessment of rapid diagnostics on antibiotic decision-making. Key themes include translating advanced technologies into clinical practice while balancing analytical performance with operational feasibility in high-volume laboratory settings.

As Associate Program Director for the CPEP fellowship, she shapes training for future clinical microbiologists while leading specialized diagnostic services covering bacteriology, antimicrobial susceptibility testing, and syndromic molecular panels at Barnes Jewish Hospital. Her leadership ensures integration of cutting-edge diagnostics with clinical care pathways.
