Research Interests: 

Numerical Analysis and Scientific Computing.

Currently, I am working with Dr. Andy Wathen on the project ``The numerical linear algebra of approximation involving radial basis functions [M7]'' . I focus on radial basis functions and linear algebra which are related to computational issues on high dimentional approximation/interpolation and some meshfree methods.

Before I joined Oxford, I worked on minimizing communications in sparse linear solvers for supercomputers in China.

Teaching: 

2011(HT): Tutor Assistant for Part A Numerical Analysis  
2011(HT): Tutor Assistant for B21b Numerical Solution of Differential Equation II  
2010(MT): Tutor Assistant for C12.1a Numerical Linear Algebra  

Further Details: 
I am serving as a math reviewer for AMS and an IT staff for the Oxford SIAM student Chapter.
I love math---mathematics is my second language,  
but I will more love mathematics without equations.

My tools are pencil,  paper and computer; 
my goal are formulas, figures and papers.
