The Department has a very active research profile, particularly with Dr Peter Arkwright jointly employed by the University of Manchester.  The Department maintains an internal database of all patients with primary immunodeficiency diseases (PID) and also contributes to the European Society of Immunodeficiencies in which Manchester has the third largest group of PID patients in the United Kingdom. The unit collaborates with other research groups locally, nationally and internationally, particularly with the Paediatric Immunology Unit at Hôpital Necker, Paris.
