Tianyi Lou 娄天依

I am on the job market now.

I defended my thesis on 26 June 2026 at LJAD.

From September 2022 to June 2026, I was a PhD student at LJAD and Institut Fourier, supervised by Indira Chatterji and François Dahmani.

Geometric group theory

Research Interests

I work in geometric group theory, with particular interests in finite-type and infinite-type hyperbolic surfaces and their mapping class groups.
