Research Interests:

*Uncertainty Quantification:  "uncertainty is anywhere",  UQ aims to include uncertainty in mathematical models and quantify its effect on output of interest used in decision making.  UQ has a variety of applications, including hydrology, fluid mechanics, data assimilation, and weather forecasting.   I study this topic with collaborators including: Akil Narayan (Utah),  Fabio Nobile (EPFL),  John Jakeman (Sandia),  Tao Tang (SUSTech),  Dongbin Xiu (Utah),  Zhiqiang Xu (CAS). In case you are interested in this topic, you are welcome to take a look at my review paper (PDF in Chinese),  and the paper is written in honor of  Prof.  Qun Lin's  80th birthday.

*Forward backward stochastic differential equations (FBSDEs): which have comprehensive applications in stochastic optimal control, computational finance, nonlinear filtering, etc.   Prof. Weidong Zhao from Shandong University is an international expert in this area. I study this topic also with Yu Fu (SDU),  Bo Gong (HKBU),  Wenbin Liu (Kent) , and Tao Tang (SUSTech).

*Numerical analysis,  Spectral methods,  Parareal,  Fractional PDEs, ect.


 

Recent news:

 

* I will give a 6-hours lecture on "Basic and recent development of UQ" in CSRC, June 19-21, 2017.
