Personal profile


I am a public health researcher with expertise in physical activity, sedentary behaviour (too much sitting as opposed to not enough exercise), health promotion, and program evaluation.

My core research focuses on adults and workplace settings. This has involved designing and evaluating ‘move more, sit less’ initiatives, and investigating the social and environmental factors (people, places, and policies) that affect workers’ moving and sitting, as well as their mental wellbeing and productivity. I am also interested in media analysis about communication of health issues, such as sitting guidelines for office workers and claims that "sitting is the new smoking" (it's not!) . My current passion project is investigating the potential for co-ops to improve food and vegetable intake in families from disadvantaged backgrounds.

I have worked on a range of multidisciplinary projects funded by different agencies, including the NSW Ministry of Health, Heart Foundation, and the World Health Organization. I was a National Heart Foundation of Australia Postdoctoral Research Fellow (2015-2017).
