Tomu Tominaga

Welcome to my home page!! I am a Ph.D student majoring social computing at SOC Research Group at Grad. School of Engineering Science, Osaka University.

I'm also participating in Humanware Innovation Program (in Osaka Univ.), a special Ph.D course financially supported by the goverment.

Anyway, I'm crazy about sports, movies, and beer :)
