Patricia Simner, Ph.D., D(ABMM), is an associate professor of pathology at the Johns Hopkins University School of Medicine and the Director of the Medical Bacteriology and Infectious Disease Sequencing Laboratories at the Johns Hopkins Hospital.

Her research has focused on understanding the epidemiology and molecular mechanisms of antimicrobial resistance of gram-negative bacteria, in particular those harboring β-lactamase enzymes. Simner is interested in novel diagnostic tools for infectious diseases and is actively involved in developing metagenomic next-generation sequencing as a diagnostic tool.

Simner is a voting member on the Subcommittee on Antimicrobial Susceptibility Testing for the Clinical and Laboratory Standards Institute. She is the Early Career At-Large Representative for the American Society for Microbiology (ASM) Council on Microbial Science, a member of the College of American Pathologist Microbiology Committee and an Editor for the Journal of Clinical Microbiology.
