Laurent Bartholdi

Laurent Bartholdi is a Swiss mathematician working in the areas of geometric group theory, symbolic dynamics, and computational complexity. He is particularly well-known for his contributions to the study of self-similar groups and amenability of groups. Currently Bartholdi is a CNRS Directeur de Recherche at Institut Camille Jordan, Claude Bernard University Lyon 1 ^[1] in France.

Bartholdi received a PhD in Mathematics in 2000 from the University of Geneva, with Pierre de la Harpe and Rostislav Grigorchuk as co-advisors. ^[2]

In June 2025 Bartholdi delivered the inaugural Paul Schupp Distinguished Lecture at the GAGTA 2025 ``Groups, Logic and Computation" conference at the Stevens Institute of Technology. ^[3]
