Biography

I am Zeyi Zhang, a second-year Ph.D. student at the School of Intelligence Science and Technology, Peking University, advised by Prof. Libin Liu.

My research interests mainly include Human Non-verbal Behavior Generation, Generative Model, and VLM. Thanks to my guide and collaborator, Tenglong Ao, we are working on generating natural and realistic human behaviour.
