The partial differential equations (PDEs) group here at OSU focuses on the analysis and applications of several nonlinear PDEs, especially those arising in fluid mechanics, geophysics, astrophysics, meteorology and other science and engineering practice. The particular PDEs that the faculty members here have worked on include the NavierStokes equations, the surface quasigeostrophic equations, the Boussinesq equations, the magnetohydrodynamics equations and other related equations. These PDEs have been at the center of numerous analytical, experimental, and numerical investigations. One of the most fundamental problems concerning these PDEs is whether their solutions are globally regular or they develop singularities in a finitetime. The regularity problem can be extremely difficult, as in the case of the 3D NavierStokes equations. The global regularity problem on the 3D NavierStokes equations is one of the Millennium Prize Problems. In addition, the PDEs group here is also interested in the numerical computations and analysis of the aforementioned PDEs.

Full Professor 
B.S., Peking University; Ph.D., University of Chicago, 1996. Nonlinear partial differential equations from fluid mechanics, geophysics, astrophysics and meteorology. Numerical linear Algebra. He is interested in the analysis, computations and applications of these partial differential equations. One issue he has been working on is whether or not these partial differential equations are globally wellposed.
