Research Focus

My research focuses on inherited predisposition to cancer. Throughout my career, I have worked to discover the genetic lesions predisposing to cancer development in families where clustering of certain cancer types is observed. Over the years, I have studied genes predisposing to the cancer of the breast, colon, ovary and prostate. Furthermore, I am currently investigating the mechanism by which inherited mutations in the gene DICER1 predispose infants to develop a range of rare tumors such as pleuropulmonary blastoma, pituitary blastoma or cystic nephroma early in their life. As a researcher-clinician, it is my belief that advances in understanding genetic predisposition to cancer will results in improved prevention and treatment options for our patients and their families.
