I enjoy teaching and I love interactions with students. In teaching, I teach students how I think and learn their views of my research fields. My current interest is to investigate numerically the propagation of noise using models of stochastic differential equations arising in various applications, especially in  fluid dynamics, biology, and finance. The research is two fold: one is to construct efficient and stable numerical methods to solve stochastic differential equations; the other is to evaluate the constructed and existing methods through theoretical analysis.
