I'm currently a Phd candidate (2024-) of the ECEO lab at EPFL, supervised by Prof. Devis Tuia. During my doctoral study, my research will focus on multi-modal and climate foundation model. Prior to that, I obtained my Bacholar's and Master's degrees both in Electronic Information School, Wuhan University. I was honored to be supervised by Prof. Wen Yang, who guided me onto the journey of scientific research and helped me harvest a bunch of research experience and outcomes on object detection and localization, especially the tiny object detection series.
