Research Interests and Activities
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
- 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.
Michael is on the editorial board of two international journals, Accident Analysis and Prevention, and BMC Public Health.
