I'm a PhD student at the University of Edinburgh, supervised by Dr. Luo Mai (primary) and Dr. Wenda Li (assistant). My research focuses on algorithm-system co-design and infrastructure for agents and multi-agent systems. I also work on reinforcement learning.
I am also interested in serverless AI systems and have joined as a core developer of ServerlessLLM. In addition, I am collaborating with UK ARIA to build a benchmark that reveals the fundamental hardware capabilities required by emerging AI workloads such as Mixture-of-Experts, test-time scaling, and agentic workflows.
My goal is to improve agentic AI workflows for both personal use and practical industrial applications, in terms of both accuracy and efficiency.
Before exploring machine learning systems, my research was in computer vision, particularly for autonomous driving and medical imaging, so I have a solid understanding of visual data and its characteristics in image and point cloud forms. With multi-modality becoming increasingly important in agentic AI workflows involving visual data, building high-performance systems requires algorithm-system co-design — as VLMs and LLMs continue to evolve, understanding how to embrace their advances and leverage them to accelerate the overall system is both interesting and important. In the world of agentic AI, where workloads are highly dynamic and complex, systems and algorithms need to work together rather than being developed in isolation as before from my perspective.
I also have research experience with 2D-mesh accelerators such as Cerebras and Tenstorrent. My undergraduate thesis focused on designing high-performance KNN algorithms for 2D-mesh accelerators.
Outside of research, I enjoy singing and playing music, and I am currently trying to build my first album. I won first prize in a singing competition during high school. The instruments closest to my heart are guitar and erhu. I have long been inspired by Kotaro Oshio, a fingerstyle guitarist whose pieces I am always learning and playing.
Musically, I grew up with Jay Chou — his album Ye Hui Mei has stayed with me since 2006, when my parents first played it in the car. On the Western side, Roger Waters and Pink Floyd shaped my taste deeply — The Dark Side of the Moon remains the album I return to most. I am also drawn to Coldplay, especially Viva la Vida or Death and All His Friends.
