I am a first year PhD student in Data Science at City University of Hong Kong (CityU), advised by Prof. Ning Miao. Before that, I earned my BEng degree at Southern University of Science and Technology (SUSTech) majoring in Computer Science. From August 2023 to March 2024, I worked as a research assistant at Peking University (PKU) under the supervision of Prof. Haoran Zhang. I was also a research internship student at the University of Illinois Urbana-Champaign (UIUC), where I was advised by Prof. Bo Li.

My research interests focus on machine reasoning, with a particular emphasis on Large Language Models (LLMs).

- We propose SafeAuto, a framework that enhances MLLMs for autonomous driving with three key contributions: a PDCE loss that maintains the autoregressive nature of MLLMs while mimicking MSE loss during training, the use of Markov Logic Networks (MLN) to encode domain knowledge and traffic rules, and a method for retrieving similar driving experiences using video data, control signals, and MLN-based environmental predicates.
