Dr. Krzyzanowska is a practising medical oncologist and a health services researcher at Princess Margaret Cancer Centre in Toronto. The overarching goal of her research program is to improve the quality of care received by cancer patients. She combines patient-level studies focusing on specific quality issues in the oncology population such as drug safety and toxicity with population-based research. This approach allows her to look at quality issues from different, but complementary perspectives. Her studies have had an impact at both the hospital and population levels. Dr. Krzyzanowska obtained her medical degree and clinical training at the University of Toronto and completed a research fellowship at the Centre for Outcomes and Policy Research at the Dana Farber Cancer Institute in Boston. In addition to her clinical and research work, she holds leadership positions related to quality of cancer care at the local, provincial and international levels.
