Katherine Tieu

I'm a first-year CS PhD of iSAIL Lab at University of Illinois Urbana-Champaign (UIUC), advised by Prof. Jingrui He.

I am interested in (1) LLM post-training, specifically in Alignment and Efficiency; (2) Agentic AI systems, particularly in designing Multi-agent Systems; and (3) Graph Machine Learning, where I had previously worked on temporal graphs.
