Research

I am Hiroaki Murayama, working on mathematical modelling of infectious diseases. I am a final-year medical student at School of Medicine, International University of Health and Welfare in Japan.

I have regularly worked with Asst. Prof. Akira Endo at the National University of Singapore on multiple studies related to infectious disease dynamics.

Previously, I served as a member of National COVID-19 Taskforce at Japan’s Ministry of Health, Labour and Welfare, where I conducted ad-hoc COVID-19 analyses.
