About Me

I am a third-year Ph.D. candidate in Computer Science at City University of Hong Kong, under the supervision of Dr. Chen Ma and Dr. Kede Ma.

I received my Master degree in Pattern Recognition and Intelligent Systems from Zhejiang University and my Bachelor degree in Automation from Northeastern University.

Prior to my doctoral studies, I gained 2.5 years of full-time work experience at Alibaba DAMO Academy, where I focused on representation learning for recommender systems.
