I am Hiroaki Murayama, working on mathematical modelling of infectious disease dynamics, epidemiology, and control. I am also a medical student in School of Medicine, International University of Health and Welfare in Japan.

Interests

Infectious Disease Epidemiology

  • Quantification of transmission dynamics and control
  • Theoretical framework construction
  • Bayesian Inference
  • COVID-19
  • Monkeypox

My research work revolves around mathematical formulation of infectious disease dynamics to contribute to public health issues. For directly transmitted diseases, each of observed cases are not independent (infector-infectee relationship), which is often referred to as dependent happening. This phenomenon leads to the need for the reconstruction of transmission dynamics in terms of mathematical modelling to account for non-i.i.d. setting.
My main interest lies in quantifying natural history, transmission dynamics, and control (i.e.,non-phermaceutical interventions, vaccine strategy, etc.) and constructing a theoretical framework in light of Bayesian inference.
