Research

Satellite Networking, Green Computing, AI, Graph Theory

My main focus is mega-LEO satellite networking: designing simple, effective algorithms for the evolving needs of users and network operators in the 6G and AI era. I aim for methods that could be evaluated and adapted for constellations such as Starlink and Qianfan, with the longer-term goal of supporting useful, widely accessible services. My broader interests include graph theory, the P versus NP question, green computing for AI, and applications of AI to cryptography, biology and medicine. My long-term hope is to contribute to research of lasting benefit to humanity, inspired by the Nobel-recognized work of Charles K. Kao and Tu Youyou.

I use mathematical optimization, graph theory and experiments to identify useful structure, develop algorithms and test new ideas. I hope to contribute rigorous research that is simple in design, effective in practice and useful beyond the laboratory.

I welcome self-motivated students and collaborators who enjoy patient, careful work on concrete research challenges, as well as discussions and joint projects with industry teams addressing practical needs. Contact: .

Research interests

Networking for Mega-LEO constellations

I study networking algorithm design for large, moving constellations: routing, resilience, semantic communication and in-orbit computing. The aim is to meet service requirements with manageable implementation costs. Related work has appeared in IEEE TMC, Wireless Communications, TCOM and TVT, and at several conferences.

Green computing for AI

Resource packing in data centers, workflow scheduling and multi-step language-model inference. I am interested in using fewer computing resources to meet a given service requirement, and in understanding the trade-offs between energy, latency and utilization.

Whether P=NP

An exploratory interest in computational complexity, grounded in specific graph and NP-hard scheduling problems. I study exact, smart, and optimal methods, and how AI and mathematical optimization may help reveal useful problem structure.

AI for cryptography

Exploring how learning-based methods can support the analysis and design of cryptographic systems, with attention to mathematical guarantees and reproducible evaluation.

Natural and life sciences

I also explore questions in the natural and life sciences, learning across fields and considering how new observations can inform useful models and methods.
