NIE Xuecheng   聂学成

Currently, I am a Research Scientist in YiTu Technology. Before joining YiTu, I obtained my Ph.D. degree in 2020 at the National University of Singapore, advised by Assistant Professor FENG Jiashi and Assoociate Professor YAN Shuicheng. I achieved both my bachelor and master degrees from Tianjin University under the supervision of Professor FENG Wei. In summer 2014, I did as a research assistant at the City University of Hong Kong with Professor LIU Zhiqiang.

 

Research Interests
