Sam Fisher


I am a second year DPhil student at the University of Oxford working under the supervision of Dawid Kielak. I completed my undergraduate and master's degrees at McGill University. My master's thesis was supervised by Dani Wise.

Research interests

I am interested in geometric group theory and, more specifically, finiteness properties of groups, fibring, ℓ²-invariants, and group rings.
