Dr Gunn is an interdisciplinary researcher. She leads an ARC funded project focussing on the role of liveability for healthy ageing and is an investigator on an Ian Potter Foundation grant looking at cycling infrastructure. Her research uses quantitative techniques to explore relationships between the built environment and liveability, and health and wellbeing outcomes. This includes active and public transport research and investigating how planning, health and economic evaluation of infrastructure can support decisions around growth area development and transport and infrastructure delivery. Research collaborations involve the Victorian Department of Transport and Growth Area Councils.
