I have a deep commitment to improving Māori health outcomes through kaupapa Māori health research. This is reflected in my career development to date, with 15 years' experience in Māori and indigenous health research, including the completion of a PhD in public health exploring the potential of rongoā Māori. The proposed postdoctoral fellowship includes a kaupapa Māori analysis of the multiple dimensions of Māori cannabis and methamphetamine use. A mixed methods approach will include key informant interviews and quantitative data analysis. Given the significant lack of kaupapa Māori health research specific to cannabis and methamphetamine use, the upcoming cannabis referendum and increasing Māori dependence on methamphetamine, this research will contribute timely, innovative and necessary knowledge that informs Māori wellbeing. The fellowship will also strengthen key areas of professional development including: te reo me ōnā tikanga, mātauranga Māori, quantitative methods and participation in national and international collaborations with senior Māori health researchers.
