About Me
I am a Research Engineer at Alibaba DAMO Academy. I obtained my PhD degree from The Chinese University of Hong Kong (CUHK) in 2021, under supervision of Prof. Wai Lam. Before starting my PhD career, I was an undergraduate at Sun Yat-sen Universy (SYSU). I have ever interned at Microsoft Research Asia, Tencent AI Lab and Huawei Noah’s Ark Lab.
