Research Interests:

Dr. Staples’ research interests include traffic safety, medical risk factors for injury and unplanned readmissions to hospital. He seeks to use the techniques of clinical epidemiology and British Columbia’s powerful data resources to improve population health.

Research Summary:

Dr. Staples’ highest impact study used 25 years of US national data and found that fatal traffic crashes were 12% higher during the annual “4/20” cannabis celebrations (JAMA Int Med 2018). This work was highlighted in over 125 media publications including TIME, Newsweek, Gizmodo, BBC radio, Freakonomics Twitter, Reuters, and the Associated Press.

A related study examining childhood pedestrian fatalities on Halloween (JAMA Pediatrics 2019) was discussed by the New York Times, the Washington Post, U.S. News & World Report, the L.A. Times, The Daily Mail (UK), and The National Post.

Other studies have examined the validity of traumatic brain injury prognostic scores in the elderly (J Head Trauma Rehab 2015; Brain Inj 2016), modeled the effects of a nationally-implemented motorcycle helmet law in Vietnam (Inj Prev 2016), and compared the risks of American spaceflight to the risks of American road travel (Am J Med 2014). His work was included in the Disease Control Priorities (3rd edition), published by the World Bank.
