Research Interests

My research program focuses on advancing the science of knowledge synthesis. Basing decisions on expert opinion or the results from one study can be misleading. Experts often recommend interventions that are ineffective and sometimes recommend interventions that are harmful. In addition, spurious or biased results may arise from a single study. Systematic reviews (or knowledge synthesis) focus on the totality of evidence and are the base unit of knowledge translation products, such as patient decision aids, policy briefs, and clinical practice guidelines. They are the cornerstone of evidence-informed practice.

My Canada Research Chair focuses on advancing methods and includes projects, such as extending the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) Statement to scoping reviews that was published in the Annals of Internal Medicine and a prospective quasi-experimental study to compare the results from rapid reviews and systematic reviews on the same topic (https://osf.io/986pc/). I co-lead projects related to enhancing methods for network meta-analysis, such as individual patient data network meta-analysis, incorporating dosages into network meta-analysis, and applying network meta-analysis to complex interventions.

Given my interest in rapid reviews, my research program also focuses on responding to the needs of decision-makers through knowledge synthesis. I have conducted knowledge synthesis at the international (World Health Organization), national (Health Canada), provincial (Ontario Ministry of Health and Long-term Care), and local (Toronto Central Local Health Integrated Network) levels.

Current Research Projects

Nominated Principal Investigator of the Strategic Patient-Oriented Research Evidence Alliance (SPOR) funded by the Canadian Institutes of Health Research. The Alliance is a pan-Canadian initiative with the potential to improve patient care through national coordination of knowledge synthesis, knowledge translation, implementation and clinical practice guidelines development. The Alliance was designed to promote evidence-informed healthcare and policy that is grounded in the principles of inclusion (all relevant stakeholders), diversity, integrated knowledge translation, co-creation of research, and transparency.

Nominated Principal Investigator of the Methods and Applications Group in Indirect Comparisons (MAGIC) Network Meta-Analysis team funded by the Canadian Institutes of Health Research Drug Safety and Effectiveness Network. Role is to lead knowledge syntheses to address queries posed by Health Canada, the Canadian Agency for Drugs and Technologies in Health, and provincial ministries of health.

Advancing the science of knowledge synthesis with a focus on Scoping Reviews, Rapid Reviews, and Network Meta-analysis.
