I was interested in functional analysis in my early years, but now I am interested in non-equilibrium statistical mechanics, especially the basic equations that should be followed in studying turbulent motion from non-equilibrium statistical mechanics. He has published papers such as Riemann Integrability in Linear Topological Space, Closed Graph Chamber Principle of M Convex Algebra, and Finite Difference Method for Higher Order Quasilinear Elliptic Boundary Value Problems. Since 1978, he has devoted himself to the theory of gas molecular motion, an important issue recognized by domestic and foreign academic circles, and has successively completed a series of papers on "Hilbert-Skok-Chapman expansions in the theory of gas turbulent motion". His research provides a new theoretical approach for studying the phenomenon of gas turbulence, and takes an important step to solve an important problem that academic circles at home and abroad have explored from many angles but have not achieved satisfactory results. 1986 was rated as a young and middle-aged person with outstanding contributions to the country. He has taught advanced algebra, real variable functions and probability theory.

The textbook "Lecture Notes on Mathematical Analysis" compiled by him is a set of textbooks with China characteristics. It attempts to introduce the basic knowledge of mathematical analysis in the language of modern mathematics, and at the same time, introduce the relationship between mathematical analysis and other disciplines (especially physics) as much as possible.
