Prof Annette Oxenius is the Vice President for Research and a Professor for Immunology at the Department of Biology (D-BIOL) at ETH Zurich. The major emphasis of the research in the group of Annette Oxenius is the analysis of cellular immunity in acute and persistent viral infections. A first area of research focuses on the molecular, cellular and functional characterization of virus-specific T and B cell responses. A second area of research addresses the question of how T cells differentiate and diversify during immune responses. A third area investigates the mechanisms that regulate of T cell responses.
