I am a medical doctor and gastroenterology resident at the Fondazione Policlinico Universitario A. Gemelli – IRCCS. Since the beginning of my residency, I have been actively involved in research on gut microbiota under the supervision of Professor Gianluca Ianiro. My work primarily focuses on the role of the gut microbiota in patients treated with immune checkpoint inhibitors (ICIs), with a particular focus on the management of gastrointestinal-related toxicities and the impact of antibiotics and proton pump inhibitors on microbiota disruption and the resulting loss of response to ICIs
