Jean-laurent Casanova MSc, MD, PhD

Jean-Laurent Casanova, MD, PhD, is a Professor and Head of Laboratory at the Rockefeller University, Senior Attending Physician at the Rockefeller University Hospital, and Investigator of the Howard Hughes Medical Institute. He is a pediatrician and immunologist by training, and in practice, has become a human geneticist investigating infectious diseases. He discovered that life-threatening infectious diseases of childhood may be caused by single-gene inborn errors of immunity. He revealed single-gene mutations that create ‘holes’ in the immune system of children who are susceptible to specific infectious diseases, yet remain normally resistant to other infectious agents.
