Research

I am Hiroaki Murayama, working on mathematical modelling of infectious diseases. I am a medical student undergoing clinical rotations in 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. Additionally, I work as a lab associate with Asst. Prof. Robbie Parks at Columbia University, focusing on environmental epidemiology, particularly in relation to climate change and weather disasters such as tropical cyclones, developing spatio-temporal models within a Bayesian framework.

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.
