He founded and oversees the continuous updating of Health Systems Evidence (www.healthsystemsevidence.org), the world’s most comprehensive, free access point for high-quality evidence about how to strengthen or reform health systems, and how to get cost-effective programs, services and drugs to those who need them. Health Systems Evidence is also now home to the Intergovernmental Organizations’ Health Systems Documents Portal, Canada’s Evidence-Informed Healthcare Renewal Portal, and the Ontario Health System Documents Portal. He also founded and oversees the periodic expansion of Health Systems Learning (www.healthsystemslearning.org), which combines online and face-to-face learning opportunities for health system policymakers and stakeholders about how to find and use research evidence and how to set agendas and develop and implement policies. He leads one of the five teams contributing to the McMaster Optimal Aging Portal (www.mcmasteroptimalaging.org), which provides the world’s best research evidence about optimal aging, specifically packaged for citizens, clinicians, public health professionals and policymakers. He teaches an undergraduate course on the politics of health systems for the Bachelor of Health Sciences (Honours) programme at McMaster, a simulations course in the same programme, and the doctoral seminar for the PhD in Health Policy programme.
