I'm currently a third-year master's student at the School of Artificial Intelligence, Beijing University of Posts and Telecommunications(BUPT), Beijing, China. My advisor is Prof. Zhuqing Jia. Previously, I received my bachelor's degree from the School of Communications and Information Engineering, Shanghai University(SHU) in 2023.
My research interests include information and coding theory, information security and their applications. Now I am seeking PhD opportunities starting in Fall 2026. Prospective supervisors please feel free to contact me at [email protected].

Research Experience
Coding Design for Robust Dynamic Distributed Storage in Heterogeneous Storage Constraints
Research Overview
Robust dynamic coded distributed storage enables
- read/write operations under server dropouts,
- update-increment privacy against collusion by any X servers
- operation completion under storage constraints.
The goal is to characterize the fundamental limits and achievable schemes for communication cost in heterogeneous storage constraints.
Main Contributions
- Characterized the fundamental limits of robust dynamic storage under partial storage constraints and proposed achievablity schemes that match the converse bound.
- Established fundamental limits of robust dynamic storage under arbitrary storage constraints, proposing a coding scheme based on message-splitting that:
- Achieves total storage optimality,
- Maintains communication load within a constant factor of fundamental limits at scale.
Non-Interactive Privacy-Preserving Linear Regression Algorithm (Undergraduate thesis)
Research Overview
Linear regression (linear transformation) is widely used in neural network training. Designed a non-interactive, privacy-preserving training scheme with low communication overhead to train a global model while protecting user privacy.
Main Contributions
Proposed a novel training framework that eliminates the need for iterative client-server interactions, reducing communication costs. It can be experimentally validated that the scheme outperforms existing federated learning methods in computational efficiency and communication load. Published a Chinese patent as the first-author student.
