Congjing Zhang

I am a third-year Ph.D. student in the Department of Industrial and Systems Engineering at the University of Washington, advised by Shuai Huang. I am a recipient of the 2025-2027 Amazon AI Ph.D. Fellowship. I received my Master's degree in Industrial Engineering from University of Washington in 2023 and Bachelor's degree in Materials Science and Engineering from ShanghaiTech University in 2021. My research interests center on large language models (LLMs) and machine learning, with a focus on uncertainty quantification, anomaly detection and synthetic data generation.
