I am a postdoctoral researcher at National Institute of Informatics (NII) in Japan, working in Prof. Shin'ichi Satoh's group. I received my Ph.D. from the University of Tokyo in 2016 under the supervision of Prof. Kiyoharu Aizawa. My research interest includes computer vision and multimedia processing. More specifically, I am interested in theory and applications of image retrieval and manga/comic image processing.
