Weng Ian (Ianna) Chan

PhD Candidate, The University of Osaka

I am a doctoral student at Osaka University, Japan, advised by Prof. Fumio Okura. My research interests lie in computer vision and generative models, with a particular focus on controllable image and video generation, diffusion models, and developing generative technologies that are more controllable, reliable, and practical in real-world applications.

I received both my M.S. in Information Science and B.Eng. from Osaka University. From July to November 2024, I completed a research internship at CyberAgent, Inc., where I worked on facial video editing.
