I am a postdoctoral researcher in A/Prof Chang Xu’s group at the School of Computer Science, The University of Sydney. I obtained a PhD degree from Peking University supervised by A/Prof Tingting Jiang and Prof Yizhou Wang. My research delves deeply into computer vision and generative artificial intelligence for human action and skill understanding, also with interdisciplinary applications in healthcare data science.
