About

I am Qijun Zhang, a third-year Ph.D. student in the Department of Electronic and Computer Engineering at the Hong Kong University of Science and Technology (HKUST), advised by Prof. Zhiyao Xie. Before joining HKUST, I received my B.Eng. in Computer Science from Tongji University in 2022.

My research lies at the intersection of computer architecture and electronic design automation, with a particular focus on architecture-level power modeling and scale-up interconnect architecture. My work has appeared in ISCA, HPCA, DAC, ICCAD, ASP-DAC, TCAD, and NeurIPS. A complete list of publications is available on my Publications page and Google Scholar.
