Dr Katrina Champion

Dr Katrina Champion is a Senior Research Fellow at The Matilda Centre for Research in Mental Health and Substance Use and Sydney School of Public Health. She is Program Lead of Healthy Lifestyles Research at the Matilda Centre and holds a prestigious Sydney Horizon Fellowship focusing on innovative approaches to improve the physical and mental health of Australian adolescents.

Dr Champion works at the nexus of disease prevention and mental health, with a focus on the bidirectional relationships between poor mental health and unhealthy lifestyle. She develops, evaluates and disseminates digital interventions to improve both physical and mental health in adolescents.

Her doctoral research focused on the prevention of substance use and related harms among secondary school students. Her PhD resulted in the development and evaluation of the OurFutures: Ecstasy & Emerging Drugs module (formerly ‘Climate Schools’), the first online school-based prevention program designed to prevent ecstasy and new psychoactive substances.

As part of an NHMRC Early Career Fellowship, Dr Champion spent two years at the Department of Preventive Medicine, Northwestern University (Chicago, US). During this time, and in collaboration with more than 20 researchers across Australia and the US, she led the development of Health4Life, an eHealth multiple health behaviour change intervention to reduce chronic disease risk and improve mental health among school students.

Her Horizon project is continuing this work to refine digital interventions for adolescents to address the Big 6 risk factors of physical inactivity, poor diet, alcohol use, smoking/vaping, screen time and poor sleep, as well as establishing a new study in high schools to improve the update of evidence-based prevention policy and practice.

Dr Champion is also leading a MRFF-funded project to develop a new parent-based intervention specifically designed to improve health outcomes of socio-economically disadvantaged adolescents.

  • Digital interventions to improve the physical and mental health of Australians
  • Preventing risk behaviours in young people (including substance use, smoking/vaping, poor diet, physical inactivity, sleep and screen time)
