Hiiii!

I am a second-year PhD student at Network Security Lab at the University of Washington, Seattle, advised by Prof. Radha Poovendran. Prior joining UW, I received my bachelor’s (joint) degree in Communication Engineering at University of Electronic Science and Technology of China (UESTC) and University of Glasgow (UofG). During my undergrad, I was advised by Prof. Lei Zhang.

Research Interests

My research interests lie broadly in security, privacy and fairness of distributed systems and machine learning. I am particularly interested in dealing with Byzantine adversaries. Currently, I am working with a group of amazing collaborators in the following topics:

• Federated Learning. Privacy, security, and fairness in large-scale Federated Learning systems.
• Security Vulnerabilities of Language Models. Inference-time defenses to adversarial attacks in LLMs.
• Distributed Consensus. Theory and appications of distributed consensus and Blockchain.
