Hiro KATAOKA

Master of Engineering & Master Informatique

Bio

I am a student in the Doctoral Program in Computer Science at the University of Tsukuba and a member of the Multi-Agent Systems Laboratory at the university. I had joined to the double diploma program between the master's program and Université Grenoble Alpes (FR) and stayed at the mOeX team at Inria when I was a master student in Tsukuba.

My main research interests is social simulation, the area to explain various phenomena in our society through multi-agent simulations. Currently, I am working in the project that considers opinions-beliefs dual propagations.
