Profile
I'm a graduate student in the Department of Physics at Kyoto University and my advisor is Prof. Shigeru Shinomoto. Currently, I am working with Prof. James P. Gleeson at University of Limerick in Ireland. I study the spreading phenomena on neural networks and social networks using mathematical models. My Google Scholar page is here.

Research interests:

complex networks, epidemic spreading, temporal networks, neuroscience

Research Experience:

  • Visiting research student at University of Limerick (Oct 2016 - Sep 2017)
  • JSPS research fellow (DC1) (Apr 2015 - Mar 2018)

Education:

  • Kyoto University M.S., Physics (2015).
