My career has focused on protein chemistry and protein imaging of molecules central to regulation and dysregulation of the immune system. I research the mechanisms by which these molecules lead to disease susceptibility and disease progression and how they can be harnessed to cure disease.
I have focused particularly on the immune effector cells, T cells and Natural Killer cells, that keep constant watch over the body and detect and kill aberrant cells, such as those transformed by viruses or cancer. But when these immune cells become dysregulated, they can cause autoimmune diseases.
In my lab, we investigate cancers such as leukemias, viruses including HTLV-1, and autoimmune disease, including multiple sclerosis and psoriasis. We aim to develop the next generation of immunotherapies to treat these conditions.
