He completed his postgraduate training in the Department of Epidemiology, Biostatistics and Occupational Health at McGill, supported by a fellowship from the Canadian Network for Observational Drug Effect Studies / CNODES.

His current program of research focuses on developing causal inference and pharmacoepidemiological methodologies, and applications of data science approaches in the large healthcare data analysis context to answer real-world comparative effectiveness research questions. His program of research is supported by grants from the Natural Sciences and Engineering Research Council of Canada / NSERC and the BC SUPPORT Unit. He supervises graduate students from both SPPH and Statistics Department.

He also conducts, supports, collaborates and implements patient-oriented research as well as pragmatic / clinical trial design and analysis.

Within SPPH, he developed and teaches a core PhD capstone course that integrates state-of-the-art epidemiological, data science, and data analytic methods. He regularly offers workshops and webinars about emerging methods nationally and internationally.
