Biography


I joined UNNC in August 2015. Before that I worked for 3 years at Xi’an Jiaotong-Liverpool University in Suzhou (PR China) and for 7 years at Max Planck Institute for Mathematics in the Sciences in Leipzig (Germany). 

Expertise Summary

I am an applied mathematician working on non-linear partial differential equations. Of my particular interest are problems with geometric “side effects”, like free boundaries and free discontinuities.

Teaching

Advanced Mathematical Techniques in ODE for Engineers (HG3MOD CN)
Linear Mathematics (G11LMA CN)

Past teaching

Differential Equations and Calculus for Engineers (HG2M13 UNNC)
Analytical and Computational Foundations (G11ACF UNNC) 
Applied Mathematics (G11APP UNNC)
Calculus (G11CAL UNNC)
Engineering Mathematics II (HG1M12 UNNC)
Engineering Mathematics I (MTH101 XJTLU)
Methods of Applied Mathematics (MTH106 XJTLU)
Partial Differential Equations (MTH210 XJTLU)

Principal research interests

Nonlinear Analysis / Partial differential equations / Free boundary problems / Free discontinuity problems
