Alessandro Sisto

I am an Associate Professor at Heriot-Watt University.

My main research area is geometric group theory, and
I'm especially interested in generalisations of hyperbolic groups.
Here is some version of my CV (updated: October 2023).

You can find more info about the GGT group at Heriot-Watt here.
I currently have two Phd students, Giorgio Mangioni, and Stefanie Zbinden. Former phd students: Antoine Goldsborough and Davide Spriano,

You may wish to take a look at my blog. If you're here because of HHSs, you may wish to have a look at the resources collected here.

Here are some incomplete lecture notes on Geometric Group Theory. Please let me know if you have comments, corrections, complaints....
Still missing:
1) chapter on free subgroups of hyperbolic groups
