Before joining Tel Aviv University in Fall 2016, I was a member of the School of Mathematics at the Institute for Advanced Study in Princeton for two years, after completing my PhD studies at the Einstein Institute of Mathematics, at the Hebrew University of Jerusalem, under the supervision of Nati Linial

ERC Project: Word Measures in Groups and Random Cayley Graphs

Research Interests: 

I study group theory, and especially combinatorial, geometric and probabilistic group theory. Many of the questions in my research involve word measures on groups: measures induced by word maps. This involves the study of free groups and their automorphism group, as well as certain aspects of the representation theory of the groups on which the word measures are induced. In the background there are problems about expansion and spectral gaps of random objects (random graphs, random surfaces, random Cayley graphs and so on). 

Upcoming Events:
