ProfilePaul-Henry Leemann is currently an Assistant Professor in Department of Pure Mathematics of Xi’an Jiaotong-Liverpool University. He graduated from PhD at University of Geneva in 2016. Prior to joining XJTLU in September 2022, he worked as a postdoc at ENS Lyon (2016-2020) and as a Scientific collaborator at University of Neuchâtel (2020-2022).
Dr Leemann's research interests lie in the intersection of geometric and combinatorial group theory, graph theory and symbolic dynamic. He is particularly interested in groups acting on rooted trees and their (weakly) maximal subgroups, limits and coverings of (Schreier) graphs, rigidity phenomenon in Cayley and Schreier graphs and graphs associated to dynamical systems.
