I am a first-year Ph.D student of R&L Group at Nanjing University (NJU), under the supervision of Prof. Qi Fan โ homepage. I obtained my M.S. in Computer Science at the University of Chinese Academy of Sciences (UCAS) in 2024 and B.S at Shanghai Jiao Tong University (SJTU) in 2021. I was also fortunate to be an internship at 01AI 
, Huawei 
, TeleAI 
, Kuaishou-Kling 
, Tecent-Hunyuan.
My research interests lie in the intersection of Computer Vision and Machine Learning. From 2021, I started to do some research on Neural architecture search and image caption. Now, I focus on designing novel applications for image/video generation, World model, 3D autoregressive-generation and other downstream AIGC tasks. Welcome to the Zhihu homepage for academic discussions in the field of image/video generation.
