Meghan Frost Davis, PhD, DVM, MPH

Associate Professor
Director, One Health Laboratory at Johns Hopkins University
Department of Environmental Health and Engineering

As a molecular epidemiologist and an environmental microbiologist, Meghan studies the interface of bacteria and hosts to reduce microbe-mediated disease in humans and animals. Her work applies the principles of one health and microbial ecology, evaluating target microbes and bacterial genes specifically and the larger microbial community (microbiome) broadly. She also evaluates non-infection outcomes, specifically asthma, from exposure to bacterial agents and their toxic products. Designing and testing interventions to combat the rise of bacterial antimicrobial resistance and both infection and non-infection outcomes related to microbial exposures in a one health context is the goal of her research career.
