Our laboratory is interested in the molecular signals that are used by the immune system to distinguish healthy from unhealthy tissue. Many of our projects focus on “unconventional” T cell recognition, involving γδ T cells, Natural Killer T cells and Muscosal-Associated Invariant T (MAIT) cells and antigen presentation by nonclassical or MHC-like proteins. Our strengths are in biochemistry, structural biology, protein engineering and cellular assays that will reveal the fundamental principles behind how effector cells of the immune system regulate human disease. We have a high level of expertise in studying molecular recognition of T cells, particularly unconventional T cells outside the canonical CD4+/CD8+ lineage and structure function of antigen-presenting molecules.
