Dr. Derry Roopenian is professor at The Jackson Laboratory and professor of medicine at Tufts University School of Medicine. He received his Ph.D. in pathobiology from the University of Minnesota, after which he conducted his postdoctoral training at Harvard Medical School. His earliest studies into the genetics and biology of histocompatibility antigens provided the molecular definitions and a conceptual framework for what is now referred to as the immunogenomics of transplantation. More recently, his extensive and continuing contributions toward understanding the biology of the so-called neonatal Fc receptor, or FcRn, and its therapeutic applications are among the most influential in the field. His current studies also delve into the genetic causes, pathogenesis and treatments of autoimmune disorders, including systemic lupus erythematosus.
