Thuy Duong Nguyen

I am an MSc student at the University of Alberta, advised by Dr. Jocelyn Chen and Dr. Xi Ye.

My research focuses on building AI agents that support and align with humans. I study language-model reasoning and develop reliable agents that learn from evolving contexts and interact with people.

Previously, I was an AI Resident at Qualcomm AI Research, where I worked with Dr. Tung Pham and Dr. Dat Quoc Nguyen.
