MODEL ORGANISMS

Research

Our intestinal tract offers an attractive environment for both beneficial and pathogenic bacteria. The beneficial bacteria of our microbiota feast on undigested foods and provide numerous health benefits. Enteric pathogens see this environment as an entry point for infection. Both groups influence each other, creating a tripartite interaction with us, the host. Understanding the regulatory processes that decide on the outcome of these encounters represents an emerging research area to combat infectious diseases. While the field has focused on protein-mediated processes, our group investigates the role of RNA-centric mechanisms in controlling microbial interactions in the gut.
