About Me

My name is Ruiheng Wang (王瑞恒 in Chinese). I am a second-year Master’s student in School of Mathematics and Statistics at Xi’an Jiaotong University, advised by Prof. Xiangyu Xu. My research interests include Embodied AI, Embodied World Models, Multimodal Models (LLMs/VLMs), 3D Vision and Generative Models.

Before beginning my Master’s studies, I received my B.S. degree in Mathematics from Xi’an Jiaotong University as a member of the First year program of “Strengthening Basic Disciplines Plan” (强基计划 in Chinese). (Ranking 1/63).

I am always happy to connect with researchers and practitioners who share similar interests. Welcome to contact me for any discussion and cooperation!
