Hello, I am currently a PhD. student in Computer Science at HCPS Lab and NPU-IWC Lab, Northwestern Polytechnical University, advised by Prof. Bo Yang.

Research Interest

Intelligent Networking via Generative AI: Develop generative AI-driven methodologies to autonomously optimize network operations, enhance decision-making, and solve complex problems within communication systems.

Network Infrastructure for Generative AI Services: Design and optimize the fundamental architecture and mechanisms of communication networks to efficiently support, accelerate, and scale the deployment of pervasive generative AI applications..
