Biography

I obtained my Ph.D. from UCLA, working with Prof. Wei Wang. I received my MPhil degree from the department of computer science, the university of Hong Kong, working with Prof. Ben Kao. I got my B.S. degree from Department of Computer Science & Technology, Nanjing University.


Research Interests

Currently, I am mainly working on applied machine learning: speaker verification/identification, recommender systems, and few-shot learning.
