Welcome!

Position (Since Aug. 2018): Black-Babcock visiting assistant professor at University of Kansas, Department of Mathematics.                                            Post-doc mentor: David Nualart.

Prior to this,  I had a short but very pleasant stay at The University of Melbourne within the research group of Andrew Barbour, Nathan Ross and Aihua Xia. (April 2-July 26, 2018)

I defended my Ph.D thesis 《Recent developments around the Malliavin-Stein approach》on March 28, 2018 at Université du Luxembourg. My thesis is devoted to the fourth moment phenomena on chaoses and the main tool is Stein’s method of exchangeable pairs coupled with some spectral consideration, see [5.01].   My advisor was Ivan Nourdin.   

I obtained a M2 (Probabilités et Statistiques) degree at Université Paris-Sud, Orsay (Sept. 2014-June 2015) supported by FMJH.  I obtained a BA degree in Economics from Wuhan University (Sept. 2007-May 2011).


 

Teaching at KU:

Fall 2019:  《MA526: Applied Mathematical Statistics I》See the Blackboard


 

Research interest: Malliavin calculus, Stein’s method, SPDEs, fractional Brownian motion, local time, limit theorems.
