Jie Qing is interested in nonlinear analysis, harmonic analysis, and partial differential equations (systems) with applications to differential geometry, complex geometry and mathematical physics. Most recently, Professor Qing has continued his research on the study of singular behavior of harmonic maps and the heat flow for harmonic maps. He continues his research on the study of the Ginzburg-Landau problem and continues to be involved in the study of the geometry of conformally covariant differential operators on 4-manifolds.
