Hello! I am a second-year graduate student from Southern University of Science and Technology (SUSTech), under the supervision of Dr. Hongxin Wei. I will be joining the Radio Lab at Nanyang Technological University as a PhD student in Fall 2026, under the supervision of Dr. Xuefeng Du. I also received my Bachelor’s degree in Statistics from SUSTech.

Research Interests

My research interests lie in reliable large language models (LLMs).

• Reliable Machine Learning: confidence calibration, conformal prediction
• Large Language Models: reinforcement learning, hallucination detection

I’m always excited to explore new research directions and am open to collaborating with excellent researchers. If you are interested in my research or simply want to chat, don’t hesitate to get in touch!
