My research seeks to understand how and why human T cells cause autoimmune diseases. Specifically, I am interested in understanding which antigens are ‘seen’ by autoreactive T cells and why those structures are recognised by auto-pathogenic T cells.
How a T cell responds to a particular antigen changes the resulting immune response. My work seeks understanding of what affects T cell function and to develop assays to detect autoantigen-specific T cells and analyse their function in vitro.

Human Immunology
The Human Immunology Laboratory has two related goals: 1) to determine how and why the immune system turns against insulin-producing cells, leading to type 1 diabetes, and 2) to develop ways to measure and prevent the disease-causing immune response.
