Currently I am the translational microbiome group leader at the Quadram Institute Bioscience where my research is focused on understanding the role of gut bacteria in health and disease of humans and animals.

Current focus of our research is on the competitive exclusion of foodborne pathogens such as Campylobacter and C. perfringens from the food chain. In collaboration with clinicians at the Norfolk and Norwich University Hospital my group is actively involved in setting up Faecal Microbiota Transplant (FMT) service for the treatment of recurrent Clostridium difficile infections. We are also exploring the role of gut microbiome in colonisation and persistence of the SARS COV-2 in the GI tract of COVID-19 patients.
