Currently, her work involves developing clinical practice guidelines around imaging technologies in prostate cancer and other guidance on the appropriate use of imaging in the care of lymphoma patients. She spent the last five years as a clinical epidemiologist at Canadian government agencies, including the Ontario Ministry of Health and Long-Term Care and Health Quality Ontario. Her work in government involved evidence-based assessments in all areas of disease.
