Research Associate Professor

University of Otago, Wellington


Michael Keall is an injury epidemiologist in the Department of Public Health. His current research interests include exposure assessment for housing, roads and vehicles, and travel behaviour. He is managing major research projects looking at the potential to reduce fall injuries in homes by fixing hazards in the home and the development of a housing quality index suited to New Zealand housing. Housing quality is thought to have a major impact on health and safety, but tends to be overlooked when the quality cannot be measured in a meaningful way. Michael has had a long involvement in the development of the New Zealand Travel Survey, which doubles as an exposure assessment instrument for informing road safety policy and as a tool to identify patterns of travel, particularly those that contribute to health issues such as obesity and global warming.

Michael is a lead researcher in the Resilient Urban Futures programme, in particular the ACTIVE study, an evaluation of cycling and walking infrastructure and encouragement in two local authorities.
