Federico Vigolo

Welcome to my home page (last updated on March 2020).
I am currently a post-doc in pure maths at the Weizmann Institute of Science, here is a CV.

You can write me at: vigolo.maths at gmail dot com.

Research interests

My main interests lie in Geometric Group Theory: I am interested in Expander Graphs and their Coarse Geometry; Actions on Metric/Measure Spaces; CAT(0) and Hyperbolic Cube Complexes.

I am in the process of diversifying my areas of expertise. I am now also interested in Dynamics; Operator Algebras; Lie/Algebraic groups; Measured Group Theory.
