I am currently a Ph.D. student at the School of Computer Science, Northwestern Polytechnical University, supervised by Prof. Zhu Wang(王柱). My research interests include mmWave sensing and multimodal foundation model.

Special thanks to Prof. Zhiwen Yu(於志文), Prof. Bin Guo(郭斌), and Prof. Zhuo Sun(孙卓) for their guidance. I also appreciate the collaboration and support from my co-authors: Wenchao Song(宋文超), Qian Qin(秦谦), Yangqian Lei(雷杨倩), Dongliang Ma(马栋梁), and Qiwen Gan(甘琪文).
