 One Health Research Team

We are always looking for talented students and post-doctoral fellows to join our team.

Meghan Frost-DavisMeghan Frost Davis, PhD, DVM
Assistant Professor
Director, One Health Laboratory at Johns Hopkins University

Department of Environmental Health and Engineering

As a molecular epidemiologist and an environmental microbiologist, Dr. Davis 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. Dr. Davis 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.
