I received my Ph.D. degree in Computer Science from New York University in January 2020, advised by Prof. Tembine Hamidou. Before that, I got my Master's degree in Pattern Recognition & Intelligent Systems and Bachelor's degree of Automation in 2015 and 2012 from Tongji University in Shanghai.

My primary research interest includes machine learning, computer vision, speech processing, and game theory. Recently, my research focuses on LLM Reward Model and LLM Human Evaluation with model-in-the-loop.

I have published 18 papers and presented at 9 international conferences. I am IEEE member and serve as Area Chair of Amazon Machine Learning Conference (2021-2023).
