RESEARCH INTERESTS

My research interests center on curvature and topology of submanifolds in Euclidean space, and applications of minimal surfaces to Riemannian geometry. For example, one of my theorems shows that compact Riemannian manifolds which have positive sectional curvature and admit codimension two isometric immersions in Euclidean space must be homeomorphic to spheres. The proof, first presented in 1978, is based upon Morse theory of the height function.

In collaboration with Mario Micallef, I gave a proof of the sphere theorem from Riemannian geometry (1988) using minimal surfaces. The proof shows that the relevant curvature for the study of stability of minimal surfaces in Riemannian manifolds is the isotropic sectional curvature. In fact, the argument shows that a compact simply connected Riemannian manifold with positive isotropic curvature of dimension at least four must be homeomorphic to a sphere. This extends an earlier sphere theorem of Berger, Klingenberg and Toponogov, which was proven using geodesics instead of minimal surfaces.
