I am an Assistant Professor at ETH.
My main research area is geometric group theory, and
I'm especially interested in generalisations of hyperbolic groups.
Here is my CV (last update: December 2017).
You may wish to take a look at my blog.
E-mail: my-last-name (at) math.ethz.ch
Where to find me:
HG J 43
The Spring 2018 Topology webpage is here : https://metaphor.ethz.ch/x/2018/fs/401-2554-00L/
I'm writing lecture notes on Geometric Group Theory. Please let me know if you have comments, corrections, complaints....
