About Me
I am a Ph.D. student in Prof. Mohit Bansal’s group (MURGe Lab) at UNC Chapel Hill. Previously, I was a Research Resident under the supervision of Prof. Viet Anh Nguyen at VinAI Research, Vietnam. I received a bachelor’s degree in Computer Science from Hanoi University of Science and Technology in 2022.
My research focuses on enhancing the efficiency and robustness of large language models (LLMs). Specifically, I aim to improve LLMs performance through effective reward modeling and enhance their robustness. Additionally, I am interested in uncertainty estimation and model calibration in LLMs.
