Alessandro Sisto

I am an Assistant 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 my CV (updated: August 2020).

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
2) references

You can find all my papers and prerints here.
