I am a mixed-methods researcher with a background in Psychology. Prior to working in public health, my research was originally focused in the areas of human-technology interactions, person perception, and the social behaviour, communication, and well-being of older adults. After completing my PhD, I worked for two-years as a paid Associate Editor for Social Behaviour and Personality: An International Journal but have since returned to research. My current public health research areas include:

  • Experiences and long-term health, disability, and wellbeing outcomes post-injury, especially for older adults and for Māori.
  • Māori experiences accessing injury-related health services long-term
  • Integration of primary, community and mental health services, and health provider burnout

I have also worked as the operations manager on the following grant-funded projects, including three externally funded longitudinal cohort studies: The HRC-funded New Zealand Prospective Outcomes of Injury, ten-year follow-up Studies (POIS-10 and POIS-10 Māori); the Trauma Outcomes Project (TOP), a collaboration with NZ Health Quality & Safety Commission; Benchmarking integrated care, teamwork & staff morale: Cross-sectional survey of health care providers in Southern NZ, following the roll-out of the PCCS (funded by Healthcare Otago Charitable Trust and WellSouth)
