Research

Stephenson Strobel is a clinician-researcher and emergency physician working across multiple emergency departments within the Niagara Health System. He holds an MD, completed residency training in Family Medicine at the University of Toronto, and earned a PhD in Public Policy from Cornell University. He is an Assistant Clinical Professor in the Department of Family Medicine at McMaster University and maintains active academic affiliations within the departments of Health Policy, and Economics. His work is grounded in frontline emergency care, giving him direct exposure to the operational, informational, and incentive frictions that shape real-world medical decision-making. His research focuses on health services and labor economics, with particular emphasis on physician behavior, information transmission in clinical settings, and the design of health systems and policy. He applies modern causal inference methods to rich administrative, clinical, and historical datasets. Current and recent projects span emergency department triage and admission decisions, urgent-care closures and downstream system effects, physician taxation and labor supply, and historical public health interventions. Across his work, he aims to bridge economic theory with institutional detail, producing policy-relevant evidence informed by both data and lived clinical experience.
