Preeti Bharaj, Ph.D.

Director of BSL3 Operations, ICPH RBL
Instructor, Department of Medicine
room RBL-2217

Work in the Bharaj laboratory focuses on the development of novel models of drug activity against bacterial and viral pathogens, including select agents, Mycobacterium tuberculosis, and SARS CoV2. In addition, we focus on the aerosol transmission of SARS-CoV2, Mycobacterium tuberculosis, with the aim to directing antibiotic drug discovery projects within the Center of Excellence in Translational Research (CETR).

Dr. Bharaj has collaborated with academic groups and commercial entities to examine drug susceptibilities pathogenesis and sterilizing agents in SARS CoV2, and in bacteria including Mycobacterium tuberculosis and Select Agents.  Research at Bharaj lab also focuses on host-pathogen interactions and innate immune responses to viruses.
