Dylan O'Sullivan

Dr. Dylan O’Sullivan is a cancer epidemiologist and a health services researcher with a background in molecular epidemiology. Dr. O’Sullivan’s research program is aimed at reducing the cancer burden across the full cancer control continuum (prevention, screening, and outcomes) with the use of existing methods and the development of novel data analytics. For primary prevention, his research includes the examination of incidence and mortality trends, population attributable risk estimation, etiologic research using data from case-control and prospective cohort studies, as well as molecular studies using novel data analytics to identify emerging risk factors and to determine biological mechanisms of carcinogens. For secondary prevention his research includes the assessment of the impact of current screening programs and risk prediction for improved screening using administrative and laboratory data. Finally, for tertiary prevention his work focuses on real-world treatment patterns and outcomes, the development of prognostic and predictive models, comparative effectiveness using real-world data, and the assessment of the impact of molecular testing on patient outcomes.
