Hello, I'm Chien Nguyen

I am a Ph.D. student in Computer Science at the University of Oregon, where I am very fortunate to be advised by Prof. Thien Huu Nguyen. Prior to this, I completed my Bachelor’s degree in Computer Science at Hanoi University of Science and Technology, under the supervision of Dr. Linh Ngo Van. Before joining UoO, I had two wonderful years working as an AI Research Resident in Natural Language Processing Group at VinAI Research, Vietnam.

My Research Interests focus on Machine Learning, Natural Language Processing and their intersection. My recent work has focused on exploring novel methods for Information Extraction tasks and Large Language Models (LLMs).

Aside from research, I am also a big fan of Doraemon and used to dream of becoming the next Dragon Warrior like Po.
