I am now working on BitIntelligence (比特智路) led by Chuanxiong Guo and Layong Luo. Please feel free to contact us, if you are interested in building scalable and performant transport ASICs and their software stack to support millions of GPUs or AI ASICs interconnect.

As a researcher, my research interests include datacenter networking, hardware acceleration, and machine learning systems. I obtained my Ph.D. degree in 2023 from Hong Kong University of Science and Technology (HKUST), supervised by Prof. Kai Chen. My thesis "Towards High-Performance Datacenter Systems with Application-Oriented Optimizations" is chosen for the Honorable Mention in the HKUST CSE Best PhD Dissertation Award (2022-23).

Before that, I received my B.S. degree with Outstanding Graduate Award in 2018 from University of Science and Technology of China (USTC).
