About me


Currently, I am a Ph.D. candidate in computer science at The Ohio State University under the guidance of  Prof. Zeyu Guo. Prior to this, I obtained my bachelor degree in Mathematics and Applied Mathematics at  Sichuan University. Also, I had a one-year background in graduate studies from the School of Electronic Information and Electrical Engineering at Shanghai Jiao Tong University.

My current research interests are primarily in theoretical computer science with a focus on coding theory, combinatorics, pseudorandomness, and applications of coding theory into cryptography. You can find some of my recent work on my arXiv page, google scholar as well as the DBLP link.

My research on list decoding and list recovery was featured in Polynomial Times, the annual magazine of the Simons Institute for the Theory of Computing. A comprehensive survey on list decoding by Kumar and Ron-Zewi is available here.

In Spring 2024, I was a long-term visitor of Simons program Error-Correcting Codes: Theory and Practice  at UC Berkeley. I was also a research intern at Toyota Technological Institute at Chicago under the guidance of Prof. Madhur Tulsiani during Summer 2025.
