Dr. Ansell’s research focuses on investigating the phenotype and activity of intratumoral T cells and developing strategies to modulate the T-cell infiltration in B-cell lymphoma. Further areas of research interest include the development of biologic therapies for non-Hodgkin’s lymphoma, Hodgkin’s disease and Waldenstrom macroglobulinemia. The current strategies being developed include the use of novel antibodies and cytokines, the use of targeted therapies, and the development of strategies to inhibit signaling through receptors that promote the survival of malignant B cells. The utility of these strategies is being tested in early phase clinical trials.
