I am a Lecturer (Assistant Professor) at School of Physics, Mathematics and Computing, The University of Western Australia. I was 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 interests lie in generative artificial intelligence, computer vision, human action and skill understanding, also with interdisciplinary applications in healthcare data science.

I am actively looking for PhD/MPhil/Visiting students and research interns. If you are interested in working with me, please feel free to contact me.
