Rongyuan Wu
PolyU, Hong Kong
I am currently a fourth-year PhD student at The Hong Kong Polytechnic University (PolyU), supervised by Prof. Lei Zhang. I obtained my M.S. degree in 2022 and my B.S. degree in 2019, both from Northwestern Polytechnical University (NPU), where I was supervised by Prof. Yongqiang Zhao.
My research interests focus on Computational Photography and Generative Models. I welcome discussions, questions, suggestions, and potential collaborations. Please feel free to reach out if you are interested in my work.
