Chen Yiwen

I am Yiwen, a third year Ph.D. student at Nanyang Technological University focusing on 3D AIGC, with S-Lab. I am fortunate to be supervised by Prof. Guosheng lin. I got my Bachelor’s degree in Computer Science at Beihang University in 2022, where I spent a wonderful time working with Prof. Si Liu.

Research

My research interests lie on 3D Generation, Gaussian Splatting, Diffusion Models. I am eager to investigate the infinite potential of AIGC.
