Research interests

I am interested in nonlinear partial differential equations arising in differential geometry, in particular the problem of isometric embeddings of Riemannian manifolds in Euclidean space. The PDE system at hand is the Gauss-Codazzi system, whose type, in the case of surfaces, depends on the sign of the Gauss curvature. There are many open questions concerning existence of isometric embeddings, particularly when the curvature is negative (giving a hyperbolic system) or can change sign (giving a mixed-type system).
