Chronic granulomatous disease (CGD) is an inherited immunodeficiency characterized by recurrent infections and inflammatory complications as a result of reduced phagocyte-mediated production of reactive oxygen species (ROS).  The most common inflammatory complication in CGD is inflammatory bowel disease (IBD), affecting almost 50% of patients, making CGD an important Mendelian cause of IBD.  My research focuses on CGD as a translational disease model to explore the role of ROS in IBD. I am particularly interested in the interplay between the intestinal microbiota and mucosal immune system in order to gain a better understanding of the pathogenesis of CGD IBD and elucidate therapeutic targets.
