About
I am a first-year PhD student at the Department of Computer Sciences, University of Wisconsin-Madison. I am currently actively looking for a professor to work with.
Prior to this, I obtained my Bachelor of Engineering from the School of Data Science and Engineering at East China Normal University. When I was an undergraduate student, I was extremely fortunate to be advised by Professor Yanhao Wang. To tell you more about my emotions and comments about my previous college, check this page.
My current research mainly focuses on theoretical computer science, data mining and social aspects of algorithm. Some of my previous research might focus on trustworthy AI.

Ruien Li, Yanhao Wang
Advances in Neural Information Processing Systems (NeurIPS)
We study diversity maximization under individual fairness constraints, proposing bicriteria approximation algorithms for max-min, max-sum, and sum-min diversification problems.
Coresets for Deletion-Robust k-Center Clustering
Ruien Li, Yanhao Wang, Michael Mathioudakis
Proceedings of the 33rd ACM International Conference on Information and Knowledge Management (CIKM)
We propose a 4-approximation algorithm for deletion-robust k-center clustering, providing a coreset of size O(kz) and demonstrating its robustness against adversarial deletions.
