Biography [back top]
I am a Postdoctoral Researcher at the Telecommunications Circuits Laboratory (TCL) of EPFL. I received my Ph.D. degree in Electrical Engineering from EPFL in 2025, under the supervision of Prof. Andreas Burg, with the thesis Efficient Algorithms and VLSI Implementations of FEC Decoders for B5G/6G. Before that, I obtained my M.S. degree from Southeast University in 2021, supervised by Prof. Xiaohu You, and my B.S. degree from Nanjing University of Science and Technology in 2018.
I have several successful tape-outs at 16 nm, 28 nm, and 65 nm process nodes. My research interests include:
- Information theory and practice
- AI-driven algorithms and hardware for B5G/6G
- Edge-AI architectures and accelerators
- AI x 6G model design and chip implementation
