About me

I am an Associate Professor at the Department of Computer Science at Takushoku University.

I received my Ph.D. from the University of Tokyo in November 2013, under the supervision of Prof. Takeo Igarashi. My work experience also includes a researcher for Japanese animation studio OLM Digital, Inc. for two years.

My research interests lie in the field of computer graphics in general, particularly Non-Photorealistic Rendering (NPR).

Keywords: Stylized Rendering, Character Animation, User Interaction, Image Analysis.
