I am a Professor in the Department of Mathematics  at the University of Connecticut. Here is my most recent CV.
 
Research experience:
My research interests are in differential geometry and partial differential equations. A significant part of my recent work has focused on the singularity formation in the Ricci flow. With Jiaping Wang, we studied the asymptotic geometry of four-dimensional Ricci solitons, roughly proving that 4d shrinking Ricci solitons must be either conical or cylindrical at infinity MW1, MW2.

I am currently also interested in understanding how scalar curvature interacts with geometry and analysis on three-dimensional manifolds. Jiaping Wang and I studied volume and spectral comparison estimates for three-dimensional noncompact Riemannian manifolds with scalar curvature bounded below MW3, MW4.

Other projects that I worked on concern Green's function estimates on noncompact manifolds MSW1, MSW2, on which I recently collaborated with Chiung-Jue Sung and Jiaping Wang. The three of us recently also studied the area and spectrum of stable minimal hypersurfaces MSW.
