EDUARDO REYES

I am a postdoctoral fellow at the Max Planck Institute for Mathematics at Bonn in the group of Ursula Hamenstädt. Starting in the Fall of 2024, I will be a Gibbs Assistant Professor at Yale University.

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 .
