Croitoru’s research is focused on IBD: investigating how intestinal inflammation occurs, especially the role of T cell effector and regulatory function in the gut mucosa. His work aims to understand how T cells maintain intestinal homeostasis in health, and the problems in regulatory T cells that allow for the breakdown of these mechanisms. Croitoru is also project leader of the CCC GEM Project ( a multi-million-dollar prospective cohort study of individuals who are at risk of developing Crohn’s disease. The project explores the genetic, environmental, and microbial factors contributing to Crohn’s disease.
