Biography

I am a PhD student in Computer Science at Case Western Reserve University, where I am fortunate to be advised by Prof. Erman Ayday. Prior to joining CWRU, I earned my M.S. in Electrical and Computer Engineering from Georgia Tech and my bachelor's degree in Computer Science from Beijing Jiaotong University.

My research focuses on LLM reasoning, Coding agents, LLM watermarking, and Genomic language models.

I am open to visiting opportunities, internships, and research collaborations. Please feel free to get in touch.
