Yuki Koyama, Ph.D.

Short Bio

Yuki Koyama is a Senior Researcher at National Institute of Advanced Industrial Science and Technology (AIST). He received his Ph.D. from The University of Tokyo in 2017, advised by Prof. Takeo Igarashi. His research fields are computer graphics and human-computer interaction. In particular, he is interested in supporting designers by using computational techniques such as mathematical optimization. He has published papers at ACM SIGGRAPH, CHI, UIST, etc. From 2021, he also started working at Graphinica, Inc., in which he is aiming at bridging art and technology in animation production. He was awarded JSPS Ikushi Prize (2017) and Asiagraphics Young Researcher Award (2021).

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 with preference learning and/or Bayesian optimization
  • Computational design for functional fabrication
  • Expressive computer animation
