My research focuses on geriatric oncology. In particular, I am interested in understanding the interaction between cancer, its treatment, and the older adult. I use different research methodologies to gain insight into this issue: prospective cohort studies to examine health effects of treatment particularly in areas of quality of life and physical function; clinical trials of supportive care (exercise, education, decision aids) to improve decision-making and/or treatment, and administrative databases to monitor patterns of diagnosis, referral, and therapy. My major foci relate to prostate cancer, acute myeloid leukaemia, and the role of geriatric assessment in older adults with cancer. A major interest also relates to understanding the toxicities of androgen deprivation therapy in men with prostate cancer.
