Gregory R. Chambers

I am an assistant professor in the Department of Mathematics at Rice University. Before coming to Rice, I was an L. E. Dickson Instructor at the University of Chicago, and a graduate student at the University of Toronto before that.

My research is in metric geometry and geometric analysis. I am particularly interested in quantitative topology, min-max theory, isoperimetric inequalities, stability estimates for geometric inequalities, and symmetrizations and their applications.

My CV can be downloaded here.
