His research investigates ethnic- and age-related inequities in colorectal cancer outcomes in Aotearoa New Zealand, spanning screening, diagnosis, treatment, and survival. Drawing on linked national datasets and ecosocial theory, his work seeks to identify structural and health-system factors that shape inequities and to generate evidence to support more equitable colorectal cancer care. His PhD is funded through this project.
