Hiro KATAOKA

Bio

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

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.
