Sai Campbell

Sai Campbell is a DPhil candidate in Population Health at Oxford Population Health, where her research examines how socioeconomic position shapes infectious disease outcomes across the UK population. Her thesis links deeply phenotyped cohort data from UK Biobank with national administrative records to trace social gradients along the full pathway from infection to death, and to test which mechanisms drive them. She is supervised by Professor Jennifer Beam Dowd, Associate Professor Ben Lacey, and Professor Alyson van Raalte.

Sai holds an MSc in Global Health Science and Epidemiology from Oxford and a Bachelor of Philosophy from the Australian National University, with a background in immunology and genetics. She has previously worked on projects concerning emergency outbreak response, emerging infectious diseases, health security, therapeutic goods assessment, and laboratory immunology across various roles in government and academia. Her work sits at the intersection of epidemiology, demography, and health policy. She is a Rhodes Scholar and an affiliate of the Max Planck Institute for Demographic Research.
