Research Interests

  • The gut immune system maintains an intimate dialogue with gut microbiota. My research focus is centered on defining conserved phylogenetic signals revealing how host immunity and exogenous factors of the gut ecosystem shape the microbiome. I am particularly interested in how host-derived immune effectors shape the dynamics of colonization. This work may contribute to our understanding of how disruption of this dynamic interaction (e.g., loss of homeostasis) at the mucosal surface of the gut relates to the onset of Inflammatory Bowel Disease (IBD) pathologies observed in humans. Our work has allowed us to develop expertise in comparative microbiome studies, which also includes studies on how microbiomes shape host physiology. Our research is supported by the NSF, the NIH, and All Children's Hospital Johns Hopkins Medicine.
