I am a postdoctoral researcher at Politecnico di Milano (PoliMI), Italy. I received my bachelor’s degree from Shanghai Jiao Tong University (SJTU), China. Besides, I received a double master’s degree from SJTU and PoliMI. I obtained my PHD degree with cum laude under supervision of Prof. Massimo Tornatore from Politecnico di Milano. I also worked with Dr. Patricia Layec in Nokia Bell Labs France as an assistant optical networking researcher in 2023. I visited the Quantum Information Team with Prof. Eleni Diamanti and Prof. Frédéric Grosshans in Sorbonne University for 3 months in 2024.

My research interests cover a broad spectrum of topics in resource allocation for optical networks, which a focus on optimization and machine learning approaches to improve the energy efficiency and network resiliency of optical networks. My current research focus is on the following two topics:

Optical Networks for Resilient Distributed Training of Large AI Models
- Multi-Generation ROADM Upgrade for Multi-Fiber Optical Networks
- Optimization of Communication and Computation for Distributed Training of Large AI Models
Green and Resilient Quantum Communication Networks
- Optimized Energy-Efficient Deployment of QKD and Quantum Networks
- Resilient Key Distribution for Fiber-based and Satellite-based QKD Networks
