About Me

I am a Machine Learning Quant Algorithm Engineer in the Quantitative Technology Department at X-tech, working on machine learning algorithms and quantitative strategy research.

I received my B.S. from the School of Information Science and Engineering, Chongxin College, Shandong University, where I was supervised by Prof. Zhi Liu. Before joining X-tech, I worked on quantitative research and AI algorithms at JoinQuant, served as a Research Assistant at HKUST(GZ) AI Thrust & INFO Hub under Prof. Yutao Yue, and conducted trustworthy AI research as a remote research intern at KAUST.

My research centers on trustworthy AI, especially concept bottleneck models (CBMs). I study editable and continual CBMs, multimodal interpretability, concept-level security, reliable time-series forecasting, medical AI, autonomous driving, and LLM interpretability. My work has been published or accepted at venues including ICLR, NeurIPS, ACM MM, ECCV, MICCAI, EMNLP, TMLR, ECML-PKDD, ICASSP, ICML, and IJCAI.

Research Areas

Area Current focus
Concept Bottleneck Models Editable, continual, robust, and secure concept-level interfaces for vision, language, multimodal, and medical systems
