    Clarissa Campbell studied Biology with a minor in Genetics at the Federal University of Rio de Janeiro (UFRJ) and subsequently earned a master’s degree from the Oswaldo Cruz Foundation (FIOCRUZ) investigating how bacterial molecules exert immunomodulatory effects on mammalian cells via nuclear receptors, a topic she would continue to explore throughout her career. She joined the Tri-Institutional Immunology and Microbial Pathogenesis Program at Weill Cornell Medical College in New York as a graduate student where she specialized in mucosal immunology and regulatory T (Treg) cell biology. After obtaining her PhD, Clarissa remained under the mentorship of Dr. Alexander Rudensky at Memorial Sloan Kettering Cancer Center to continue her work on host- commensal interactions and pursue broader scientific questions bridging the fields of immunology and metabolism. Her research has characterized a circuit whereby microbial metabolites including short-chain fatty acids and secondary bile acids facilitate the differentiation of peripherally induced Treg cells, which in turn suppress immune responses to colonization and preserve a niche for a group of intestinal bacteria. More recently, she found that a bile acid-sensing nuclear receptor contributes to the cell-intrinsic responsiveness of effector T cells to fasting. Clarissa Campbell joined CeMM as a principal investigator in July 2021. Her lab is interested in investigating how changes in microbial and organismal metabolism contribute to regulate immune cell function.
