Biography

I am currently working on LLM algorithm-system co-optimization. I obtained my Ph.D. in 2023 from The Chinese University of Hong Kong under the supervision of Prof. Evangeline F.Y. Young, where I also served as a Postdoctoral Fellow. While my early research focused on GPU-accelerated VLSI EDA, I now work on bridging the gap between high-performance system and large-scale model.
