We are interested in understanding how mast cells recognize beneficial and pathogenic microbes to maintain tissue homeostasis and educate the immune system. Our lab uses an interdisciplinary approach that combines mouse and microbial genetics, receptor pharmacology, sequencing, multiparameter flow cytometry, microscopy, and infection models to elucidate how the G protein-coupled receptors expressed by mast cells act as sensors of the communication between host and microbes. Our ultimate goal is to guide fundamental knowledge necessary for developing next-generation therapeutics for infectious and inflammatory diseases.

Healthy gut microbiota can be disrupted due to antibiotic treatment, intestinal inflammation, or changes in diet. Targeted restoration of the microbiota will require an understanding of how genomic diversity between closely related microbes influences their ability to drive beneficial functions. To address this, our laboratory will use a large collection of whole-genome sequenced isolates to understand how variation between closely related gut isolates alters their ability to prevent pathogen expansion and maintain homeostatic interactions with the mucosal immune system.
