The HERO group's primary fields of research are health economics, health technology assessment and health equity. Our goal is to combine our knowledge and experience in these areas to improve population health outcomes; reduce health care disparities in vulnerable and marginalized populations; and efficiently allocate health care resources.

Examples of our research projects include: the economic impact of multimorbidity in Ontario; the impact of the maximum quantity policy on prescribed drug expenditures; economic burden of HIV/AIDs in Ontario; and cost-effectiveness analysis of health care interventions such as pharmacist-led smoking cessation, diabetic retinopathy and glaucoma screening, and routine eye examination. In addition, they have been involved in systematic review and meta-analysis projects, for example a systematic review of fall prevention programs in elderly population and a systematic review of turmeric in the treatment of digestive disorders.
