I am currently the Research Scientist in HyperGAI. My research direction lies in vision-language and multimodal ai. I used to work on object detection and food computing during my PhD and Postdoc career. I have published some papers in ICLR, CVPR, MM, and KDD, and have served as the PC member for these top-tier conferences. I obtained my B.A from Zhejiang University and Ph.D from Singapore Management University.
