I am a first-year phd student (2025 fall) at the School of Information Science and Engineering, Southeast University, under the supervision of Prof. Yu Han and Prof. Shi Jin. I also serve as a reviewer for top-tier journals, including IEEE JSAC, IEEE TSP, IEEE TMC, IEEE IoTJ, IEEE TNSE, and IEEE WCL.

Research Area

My research focuses on radiomap modeling and learning for wireless systems, with an emphasis on generalization, physical consistency, and structured representations.

DRL-LANCP (Link: IEEE TMC) investigates how to improve the generalization of low-altitude radio map prediction by disentangling propagation-related representations, bridging data learning with implicit physical structure.

RadioGAT (Link: IEEE TWC, code) studies how to perform reliable cross-band radio map prediction when measurement data are sparse and irregularly distributed, by learning wireless spatial correlations in a graph-based manner.
