Faculty at BITZH

Bio

I am Kecheng Huang (黄克成), a Tenure-Track Professor (Teli Young Fellow) at Beijing Institute of Technology, Zhuhai in Computing Science Group, Aerospace and Informatics Domain. I am currently seeking candidates for several positions, including Postdoc, PhD, Master, and Undergraduate Interns. My research interests encompass novel computer architectures, system designs, databases and AI4Sys & Sys4AI. For inquiries or collaborations, please feel free to reach out to me at hkc@bit.edu.cn.

I was a post-doctoral fellow in the CSE Department at The Chinese University of Hong Kong (CUHK), under the supervision of Prof. Zili Shao. I obtained my PhD degree at CUHK in 2025, also guided by Prof. Shao. During my doctoral studies, I engaged in sustained research collaborations with both academia (Prof. Feng Chen at IUB and Prof. Tong Zhang at RPI), and industry partners (Huawei Hong Kong Research Center and Huawei Storage Product Line).
