Dr. Sullivan's research focuses on new and rare immunodeficiencies. She has a long-standing interest in one of the most common of the primary immunodeficiencies – chromosome 22q11.2 deletion syndrome. She also investigates common variable immunodeficiency, as well as the genetics and epigenetics of systemic lupus erythematosus.
Researchers from the Center for Applied Genomics at The Children’s Hospital of Philadelphia investigating a serious, rare disease called common variable immunodeficiency have discovered a gene linked to immune defense.
The Inflammation and Immunity Lab has a broad interest in immune dysfunction. This can underlie susceptibility to infections and autoimmunity and inflammation. The investigators in the lab use cutting-edge approaches to investigate cause in individual patients and to look at population-wide causes of disease.
