About

I’m a first-year CS Ph.D. student at Luddy School, Indiana University Bloomington, advised by Prof. Chenghong Wang. I received both my Bachelor’s and Master’s degrees from Chongqing University, working with Prof. Bin Cai, Prof. Chunqiang Hu, and Dr. Jiajun Chen.

My research interests lie in data privacy and security. In the past, I worked on applying differential privacy to graph data. Lately, I’ve been exploring private SQL query algorithms and system design for secure data processing. I’m also increasingly interested in cryptography and its role in enhancing privacy guarantees.
