My Research

Our studies focus on bacteria of the human microbiome including Campylobacter and Helicobacter species that live in the mucus layer overlying the mucosal epithelium of mammals, including humans. Specifically, we explore the biology of colonization and the nature of the interactions that lead to (or protect from) disease. For the normal microbiome, we study how early life perturbations affect host developmental phenotypes. Our on-going work focuses on the metabolic syndrome, and specifically on obesity and type 2 diabetes, as well as inflammatory disorders such as type 1 diabetes, asthma, psoriasis, and skin infections.
