Biography

Our research interests center on understanding cancer pathogenesis and the immune response as a way to define new targets for therapy. Past work has defined the family of tyrosine kinase enzymes including Bcr-Abl and its role in human Chronic Myelogenous Leukemia and Bruton’s tyrosine kinase as regulator of lymphocyte growth control. This has helped enable the development of drugs like Imatinib and Ibrutinib now used in the treatment of multiple leukemias, lymphomas, and other cancers. More recent research has centered on epithelial cancers including prostate cancer. We have defined surface antigens like PSCA and others as targets for monoclonal antibody or chimeric antigen receptor T-cell mediated therapy. A fundamental understanding of normal prostate development and stem cells is used as a comparison to the process of prostate cancer development, metastasis, and conversion to its aggressive castration resistant form. We have defined specific kinases and their pathways that point towards new targets for therapy, as well as a developmental change of tumors in response to therapy that drives the evolution of a very aggressive small cell histology with neuroendocrine features. In many of our studies we employ advanced imaging technologies including Positron Emission Tomography to monitor specific cell populations and aspects of tumor and immune response metabolism.
