I am a PhD student majoring in computer science at the School of Computing, National University of Singapore. I am fortunate to be advised by Reza Shokri. My research interests lie in in Data Protection and Privacy in Machine Learning. Here is my CV (until Jan 17 , 2023).

I am currently doing a research internship at Apple ML Research. Previously, I was a research intern at Azure Research - Microsoft Research. I received my B.S. degree in computational mathematics at University of Science and Technology of China, where I had a memorable time.
