Stefanie Zbinden

I am a PhD student under the supervision of Alessandro Sisto at Heriot-Watt University. I graduated with a Master's degree from ETH Zürich.

I am interested in geometric group theory. In particular groups with hyperbolic features and their boundaries.

I am an active member of the competitive programming community. I have participated at several competitions (among others IOI and ICPC). I was the main organizer of the first EGOI and am part of the IC of EGOI since then.
