Welcome to Rongxing Xu's Home Page

Xu (徐), Rongxing (荣兴)

I am a lecturer at Zhejiang Normal University. I was a postdoctoral fellow at University of Science and Technology of China (during 07/2021-06/2023) under the supervision of Prof. Jie Ma. I obtained my Ph.D. degree in 2021 from Zhejiang Normal University under the supervision of Prof. Xuding Zhu. During the Ph.D. studying peorid, I receieved CSC Scholarships in 2018, which supported me to visit University of Paris 7 and worked with Prof. Reza Naserasr for 24 months (10/2018 - 09/2020). I got my M.S. degree from Zhejiang Normal University in 2017 under the supervision of Prof. Xinzhong Lv, Prof. Guixian Tian and Prof. Xuding Zhu. Back in 2014, I got my B.S. degree from Henan University.
