EDUARDO REYES
I am a Gibbs Assistant Professor at Yale University. Previously, I was a postdoctoral fellow at the Max Planck Institute for Mathematics at Bonn in the group of Ursula Hamenstädt.
I am interested in geometric group theory and its interactions with low-dimensional topology, geometric topology and dynamics. I like studying hyperbolic groups and their generalizations, groups acting on CAT(0) cube complexes, and deformation spaces of isometric actions.
I received my PhD from the University of California, Berkeley. My advisor was Ian Agol.
Before coming to Berkeley, I received my bachelor's and master's degree from Pontificia Universidad Católica de Chile under the supervision of Jairo Bochi. Here is my CV .
In the Spring of 2025, I am co-organizing the Geometry and Topology seminar with Tam Cheetham-West. On April 26, Brown is hosting GATSBY.
