Dr Caitriona Murphy joined the School of Public Health as Post-doctoral Fellow in 2025. She was trained as a microbiologist in Ireland before spending two years researching the burden of RSV in infants in Zambia. She later earned her MPH and PhD at the University of Hong Kong and has since continued her research on the epidemiology of respiratory viruses, including influenza and COVID-19. Her primary research focuses is on the effectiveness of control measures, including diagnostics, non-pharmaceutical interventions and vaccination.
