My research interests include: global carbon cycle, terrestrial water dynamic; urban climate. I use satellite remote sensing data, reanalysis data, as well as terrestrial biosphere models to advance solutions to important environment questions. My current project is to use multiple photosynthesis tracers to advance our predictive understanding of GPP using NCAR CLM5


About me

I am a PhD student in Ying’s lab. Prior to joining Ying’s lab, I obtained my bachelor and master degrees from Nanjing University in Dr. Wenfeng Zhan’s lab. I did several researches using satellite land surface temperature products to monitor the spatiotemporal patterns of urban heat island, and explore the underlying mechanisms.
