I am a physician-scientist that focuses on translational laboratory-based cancer research with a particular emphasis on hematological malignancies and on cancer predisposition syndromes. Another major research interest is centrosomal biology and chromosomal aneuploidy and its roles in developmental biology and cancer. These two interests are merged in the study of leukemias associated with germline aneuploidy (Down Syndrome).
We combine advanced genomic approaches with functional pre-clinical models. Several of our discoveries proved to be of general importance to children and adults with acute leukemias. These include the discovery of ERG as an important hematopoietic oncogene, in addition to its known role in prostate cancer, and the discoveries of unique activating JAK2 mutations and of mutational activation of the cytokine receptors to TSLP and interleukin 7 in acute lymphoblastic leukemias (ALL).
These findings have led to new diagnostic tests and clinical trials of ALL in adult and children. Our more general cancer-aneuploidy and centrosomal biology research has been promoted by our discovery of STIL (previously named SIL), a gene disrupted in T-ALL, is a major centrosomal duplication factor in mammalian cells. We study how STIL, centrosomes and the hedgehog pathway are involved in development and cancer. We are developing novel therapeutics targeting the STIL pathways for epithelial cancers, for example ovarian cancer. This line of research reflects the integrative nature of current cancer research focusing on biological processes in addition to specific types of cancers.
Our research of Down Syndrome and of STIL (that is involved in autosomal recessive microcephaly) have led me to further develop my research interest in congenital and hereditary disorders predisposing to cancer. Germline variants are increasingly recognized as key players in cancer. We are currently studying human pedigrees and creating mouse models of such germline driven disorders. These studies have been funded by multiple national and international grants and have involved multiple national and international collaborations in both basic and clinical research with scientists and clinicians in North America, Australia, Japan and Europe.
