Biography

I am a Postdoctoral Fellow at The Chinese University of Hong Kong. I obtained my Ph.D. degree from CUHK in 2023 under the supervision of Prof. Evangeline F.Y. Young, and my B.Eng. degree from South China University of Technology in 2019. My earlier research focused on GPU-accelerated VLSI EDA. Currently, I am primarily working on LLM algorithm-system co-optimization and LLM-assisted combinatorial optimization.
