About me
I am a first-year PhD student at Imperial College London, advised by Prof. Wayne Luk and Dr. Hongxiang Fan. I am a recipient of the President’s PhD Scholarship at Imperial. Previously, I completed both my bachelor’s and master’s degrees at Imperial College London.
My research focuses on bridging the gap between advanced AI algorithms and hardware platforms through efficient hardware-aware algorithms, cost-effective model merging, ML-assisted hardware design, and algorithm-system co-design. My current research directions include:
- Multi-token generation for LLMs
- LLM quantization for edge deployment
- Model merging
- Code agents for hardware design
Education
- Ph.D in Computing Research, Imperial College London, 2024 - 2028 (expected)
- MEng in Computing, Imperial College London, 2020 - 2024
