Ziyu Wan (万子钰)

I am a Member of Technical Staff at Microsoft AI Superintelligence. We post-train O-series and GPT-5 models.
I received my Ph.D. from Department of Computer Science, City University of Hong Kong in 2024, where I was fortunate advised by Prof. Jing Liao.
My current research interests include:

Multi-modality (text, image, video, 3D and 4D) generation
Computational Photography
Neural Rendering
