Jeffrey Letourneau

I am a PhD student in the Molecular Genetics and Microbiology (MGM) department interested in how gut bacteria interact with each other and their host. In the David Lab , I study how bacteria metabolize dietary fiber and how altering the gut microbiome can effect physiological and psychological changes in humans.

Before coming to Duke, I received my BS in Biology & Biotechnology from Worcester Polytechnic Institute (WPI) in Massachusetts. My undergraduate thesis (or MQP , in WPI-speak) in the Rao Lab focused on interactions between Candida albicans  and host macrophages.

Current Research Interests

Human gut microbiome, dietary fiber metabolism, gut-brain axis, in vitro models of bacterial communities, computational biology, pediatric gut microbiome, gastrointestinal disorders, human dietary interventions, food science, host-microbial interactions, infectious disease
