About me
I am a fourth-year undergraduate at CUHK-Shenzhen (The Chinese University of Hong Kong, Shenzhen), currently working on large-scale pretraining infrastructure. I am a WeLM pretraining infrastructure intern at Tencent WeChat Group, following a summer internship in video generation pretraining infrastructure at Kling AI.
During my undergraduate studies, I have been very fortunate to be advised by Yang Zhou and Yunming Xiao.
