Dan A. Lee


I am an Assistant Professor of Mathematics at Queens College, CUNY.  My main field of research is geometric analysis, specifically the use of partial differential equations to solve problems in differential geometry.  My current work focuses on the study of scalar curvature and geometric aspects of general relativity, and my NSF grant is titled, “The notion of mass in general relativity and Riemannian geometry, and other topics.”  But in general, I’m willing to work on any mathematical problem that I find interesting.

Photos above, clockwise from left: me; some of my favorite formulae; a Calabi-Yau manifold; a Riemann minimal surface (from Weber’s website); a Schwarzschild black hole.  These are all things that I know at least a little about.

I received my PhD from Stanford in 2005, under the direction of Rick SchoenClick here for my CV.
