Biography

I am a PhD student in Computer Science and Engineering Department, The Chinese University of Hong Kong (CUHK), supervised by Prof. Chi-Wing Fu. Before that, I got MPhil from The Chinese University of Hong Kong and Bachelor from Shanghai Jiao Tong University (SJTU). My research interest includes Language and Vision, 3D Understanding and Generation.
