Research summaryInjury epidemiology

Research

Michael is an injury epidemiologist who has been working for the University of Otago, Wellington since 2006. His research interests include: home injury prevention, road safety, and exposure assessment (assessing structural environmental risks).

He is currently leading the Home Injury Prevention Intervention, a major randomised controlled trial funded by the NZ Health Research Council that is looking at the effectiveness of repairs to home injury hazards as a means to reduce home injury. He is a principal investigator in two major research programmes hosted by the University of Otago, Wellington - He Kainga Oranga and the New Zealand Centre for Sustainable Cities.
