Xiaofeng Hou

I am an assistant professor in the Department of Computer Science and Engineering, Shanghai Jiao Tong University (SJTU). At SJTU, I’m a member of Emerging Parallel Computing Center (EPCC) and Sustainable Architecture and Infrastructure Lab (SAIL). Prior to joining SJTU, I worked with Prof. Kwang-Ting CHENG at the AI Chip Center for Emerging Smart Systems (ACCESS), Hong Kong University of Science and Technology (HKUST). I earned my PhD degree from Shanghai Jiao Tong University under the joint supervision of Prof. Chao Li and Prof. Minyi Guo. I earned my BS degree from Dalian University of Technology (with honors).

I am working on deploying and implementing efficient and sustainable computer architectures and systems. My primary research focus is on developing efficient system and architecture co-design techniques for intelligent computing platforms spanning different scales. These platforms range from autonomous embedded systems (AES) for Artificial Intelligence of Things (AIoT) to advanced datacenters including microscale, hyperscale, and hybrid datacenters. I am also interested in studying and understanding their unique non-computational and computational requirements. As a result, my research encompasses a wide range of topics such as power and energy management, AI infrastructures, automated architecture and system design, sustainable computing, carbon neutrality, etc.

A Message for Prospective Students:

I’m looking for bright and self-motivated PhD, Master and Undergraduate students who have a strong interest in computer architecture and system design.

If you want to work with me (or just discuss your brilliant idea with me), please feel free to send me an email [hou-xf (at) cs.sjtu.edu.cn] along with your CV to arrange an appointment.
