My role at the APC Microbiome Institute is a research fellow in the Gut Phageomics project (Microbes to Molecules research theme). The goal of our project is to get insights into the composition and physiological significance of diverse and complex communities of bacterial viruses (bacteriophages) colonizing the human gastro-intestinal tract. We employ state of the art genomics, metagenomics and culturomics approaches to identify possible roles of bacteriophages in the maintenance of gut homeostasis, as well as perturbations of human gut phageomes in various disease states, such as inflammatory bowel disease, cystic fibrosis, C. difficile infection and many others.
