Hi, I’m Hao! I’m a Research Fellow at the School of Computing, National University of Singapore. I am currently working with Prateek Saxena in the KISP Lab. Before that, I received my Ph.D. (supervised by Prof. Jian Yan and Prof. Linling Kuang), M.S. (supervised by Prof. Jian Yan and Prof. Jianhua Lu), and B.S. degrees from the Department of Electronic Engineering at Tsinghua University, where we worked on Tsinghua’s space network communication satellite, the world’s first medium-Earth-orbit (MEO) space-based networking satellite.

My research centers on next-generation satellite communication networks and in-space intelligent systems.

• Satellite Communication Networks. We design scalable satellite network architectures, traffic engineering and routing algorithms, and programmable hardware systems to improve quality of service, resource utilization, and robustness in large-scale low- and medium-Earth-orbit satellite constellations.

• In-Space Intelligent Systems. We investigate the integration of machine learning into satellite networks and computing infrastructures, focusing on task scheduling and resource management under stringent energy constraints and highly dynamic network topologies.

• Satellite Security and Privacy. We study security and privacy challenges spanning modern satellite communication systems and the broader computing stack that supports them. We also explore trustless memory access at the processor and OS layers (CAPSTONE).

Openings for prospective students and postdocs. We are recruiting Ph.D. students (Fall 2027, Fudan University) as well as postdoctoral researchers who are passionate about satellite networking and security. If you are interested, please email me your CV and relevant materials.
