The Technion is hosting Nir Lazarovich, an associate professor in the mathematics department, as a visiting professor at the UMPA of ENS de Lyon from September 1 to 30, 2026. This visit, initiated by host researcher Adrien Le Boudec, represents a significant scientific opportunity for the Lyon-based laboratory.
Holding a Bachelor of Science in mathematics from the Technion in 2009 and a doctorate obtained in 2015, Nir Lazarovich completed a postdoctoral fellowship at ETH Zurich before joining the Technion as a Senior Lecturer and later an associate professor in 2023. His research focuses on geometric group theory and low-dimensional topology. He has been recognized with the Haim Hanani prize and the Adams Fellowship from the Israel Academy of Sciences and Humanities.
The arrival of Nir Lazarovich, a recognized specialist in hyperbolic groups and cubic complexes, is particularly beneficial for UMPA. His work, closely linked to that of Adrien Le Boudec, centers on the study of abstract commensurators of groups and irreducible lattices in locally compact group products. This joint project aims to deepen the understanding of hyperbolic group structures and open new research avenues.
Beyond scientific advancements, Nir Lazarovich's expertise will directly benefit doctoral students in the 'Geometry, Groups, and Dynamics' team. He will also contribute to the laboratory's scientific animation by participating in the team's seminar and the 'Action!' working group, where he will present his recent work on hyperbolic groups and lattices in tree products.
His major publications include articles in journals such as the Journal of the European Mathematical Society, Transactions of the American Mathematical Society, and Journal of Topology, covering topics like the rigidity of hyperbolic groups and the flexible stability of surface groups.
