I am an assistant professor in the Jarvis College of Computing and Digital Media (CDM) at DePaul University. I earned my Ph.D. in Computer Science from the University of California, Riverside (UCR), under the supervision of Yan Gu and Yihan Sun. Prior to that, I received my B.E. in Computer Science from ShanghaiTech University. In the Fall of 2025, I was fortunate to be a research fellow at the Simons Institute for the Theory of Computing at the University of California, Berkeley, for the Algorithmic Foundations for Emerging Computing Technologies program.

My research goal is to design efficient and scalable parallel graph algorithms. My research focuses both on improving theoretical bounds and providing high-performance software.
