Overview

As a molecular epidemiologist and an environmental microbiologist, I study the interface of bacteria and hosts to reduce microbe-mediated disease in humans and animals. My work applies the principles of one health and microbial ecology, evaluating target microbes and bacterial genes specifically and the larger microbial community (microbiome) broadly. I also evaluate 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 my research career.
