A/Prof Stuart Mannering completed his PhD, in 1998, on human Dendritic cells with Prof Derek Hart. For his first postdoc he went The University of Melbourne where he worked with A/Prof Christina Cheers on T-cell responses to mycobacterial infection. Then he moved to the Walter and Eliza Hall Institute to join Prof Len Harrison’s group and work on human T-cell responses in type 1 diabetes (T1D). In 2008 he established his group at St. Vincent’s Institute of Medical Research where he continues to study human T-cell responses associated with T1D. The major focus of his group’s work is to dissect the immune pathology of human autoimmune T-cell response that causes T1D.
