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.
Dr. Jyonouchi, is an attending physician with the Division of Allergy and Immunology and the Center for Cornelia de Lange Syndrome and Related Diagnoses at Children's Hospital of Philadelphia. His research focuses on immunodeficiency in Cornelia de Lange syndrome and other genetic syndromes, and asthma.
Dr. Kelsen’sresearch focus is on the genetic, immunologic, and microbiomic causes of very early onset inflammatory bowel disease. Through a multidisciplinary team approach, Dr. Kelsen and her colleagues perform genetic sequencing to identify causative genetic variants in children with VEO-IBD, study the function of these variants, and use this information to improve the clinical outcomes for these children.
Dr. Bunin's current research focuses on the development of hematopoietic stem cell graft engineering for allogeneic transplantation to minimize graft-versus-host disease (GVHD), promote engraftment and immune reconstitution. She has also developed protocols for rapid manufacture of viral cytotoxic T lymphocytes to treat or prevent life threatening viral infections post hematopoietic stem cell transplant.
