Ramnik Xavier, MD, PhD, chief of the Gastrointestinal Unit, core faculty of the department of molecular biology and director of the MGH Center for Computational and Integrative Biology, has been named a core member of the Broad Institute. Core institute members are deeply engaged in the intellectual life of the Broad and help set the institute’s scientific direction. In his new role as a core institute member, Xavier will help expand Broad’s immunological research. He will help bring together scientists across the Broad community – including those working on cancer, psychiatric illnesses, metabolic disease and infectious diseases – interested in the immune processes that play key roles in both healthy and disease states. Xavier will continue his research aimed at a better understanding of Crohn’s disease and ulcerative colitis, based on the soaring number of genes now known to be implicated in the two immune-related disorders and role of the micro biome in autoimmune disease.
