Prof Hart has made pioneering contributions to his special interest in dendritic cells (DC), immunotherapy and BMT. He is a Rhodes Scholar and RCPA Distinguished Fellow. Prof Hart recently established the University of Sydney, DC Biology and Therapeutics Group at the ANZAC Research Institute with translational sites at the RPA, Westmead and Concord Hospitals. His human DC research program was the first to clone several CD antigens and define several human DC subsets. The Group continues to define DC cell surface antigens, study DC subset function and novel gene deleted and preclinical humanized mouse models, as it develops diagnostic and therapeutic antibodies to DC.
