Yuki Koyama, Ph.D.

Short Bio

Yuki Koyama is a researcher at National Institute of Advanced Industrial Science and Technology (AIST), where he is a member of Media Interaction Group and working with Masataka Goto. He received his Ph.D. from The University of Tokyo in 2017, advised by Takeo Igarashi. His research fields are mainly computer graphics and human-computer interaction. In particular, he is interested in enhancing design activities by using computational methods. He was awarded JSPS Ikushi Prize in 2017.

Research Interests

My research interests lie on the cross-disciplinary field between Computer Graphics and Human-Computer Interaction. In particular, I am interested in

  • Computational design driven by
    • Aesthetic criterion
    • Functional criterion
  • Physically based animation
