Biography
I graduated from Tsinghua University in July of 2016 where I got my PhD degree, after that I moved to Norway working as a postdoc from August of 2016 to August of 2019 in Norwegian University of Science and Technology, then I joined in Lanzhou University as an associate professor since September of 2019. From Decmember of 2019 to December of 2020, I was a visiting postdoc in University of Paris-Saclay. Now I am a full professor in Lanzhou University from December of 2020.

Research interests
My research interests focus on the topics of non-existence, blowup phenomenon, well-posedness, long time existence and scattering of solutions of certain partial differential equations from compressible fluid and dispersive family, particularly, compressible Navier-Stokes equations and fractional Korteweg–de Vries equation.
