My research interest includes Partial differential equations and analysis with a focus on the study of nonlinear wave equations. I have
been working on Cauchy problem for quasilinear wave equations, including breakdown criterion for Einstein vacuum equations, local well-posedness of solution for very rough data and global nonlinear stability of Minkowski space with cerntain matter fields.
