Richard Bamler

UC Berkeley, USA

Jointly in sections 6, 10

Richard Bamler is a Professor at the Department of Mathematics at UC Berkeley.

He received his undergraduate education at the University of Munich, where he was mentored by Prof. Bernhard Leeb. In 2011, he obtained his Ph.D. under the supervision of Prof. Gang Tian at Princeton, and between 2011-2014 he was a postdoc at Stanford University.

His field of research is geometric analysis and he is particularly interested in Ricci flows.

Some of his work --- in part with Bruce Kleiner --- is aimed at studying geometric-analytic aspects of Ricci flows (with surgery) in dimension 3. This has led to a number of topological applications, such as the resolution of the Generalized Smale Conjecture. More recently, he has devised a new theory that allows the study of singularity formation in higher dimensional Ricci flows.
