Nicole M. Parrish, Ph.D.
Associate Director, Johns Hopkins Hospital Medical Mycobacteriology
Associate Professor of Pathology
Research Interests: Drug development; Diagnostics; Tuberculosis
Dr. Nicole Parrish is an associate professor of pathology at the Johns Hopkins University School of Medicine. Dr. Parrish serves as the associate director of medical mycobacteriology at The Johns Hopkins Hospital.
Dr. Parrish’s research focuses on characterizing the mechanism of action of a novel class of antimycobacterial compounds, including multi-drug resistant strains. She is studying how to develop new and improved diagnostic tests for detecting mycobacteria in clinical samples.
Dr. Parrish received her undergraduate degree in history and sociology from Shepherd College. She earned her masters in immunology and infectious disease and a Ph.D. in molecular microbiology from Johns Hopkins University. She completed her postdoctoral fellowship in medical microbiology from Johns Hopkins University.
A diplomate of the American Board of Medical Microbiology, Dr. Parrish also serves as an ad hoc reviewer for the Journal of Clinical Microbiology and for grants given by the National Institute of Allergy and Infectious Disease’s grants. Her work has been recognized with numerous honors, including two patents.

Research & Publications
Dr. Parrish’s research is related to tuberculosis, with a particular interest in emerging multi-drug resistant and extensively drug resistant tuberculosis strains. Her research focuses on uncovering novel compounds with potent antimycobacterial activity and developing rapid diagnostics for the detection of drug resistance. She and her team use a variety of methods, including proteomics, protein and lipid biochemistry as well as current molecular techniques.
