Yuxing Long | 龙宇星

I am a first-year PhD candidate in Center on Frontiers of Computing Studies (CFCS) at Peking University, advised by Prof. Hao Dong. Before this, I obtained my Bachelor's and Master's degrees from Beijing University of Posts and Telecommunications (BUPT).

My research interests include embodied navigation, multimodal pretraining, and multimodal conversation.
