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

Research Interests: 
  • Free Groups: word maps and word measures, Aut(F), representations
  • Expansion: expansion in random graphs, expansion in Cayley graphs, Ramanujan graphs, expansion in Lie groups
  • Combinatorial and Geometric Group Theory
  • Combinatorics and Graph Theory


  • Expansion of Random Graphs: New Proofs, New Results[journalarXiv]
    Inventiones Mathematicae, 201 (3), 845-908, 2015. 
  • Stalling Graphs, Algebraic Extensions and Primitive Elements in F2. With Ori Parzanchevski. [journalarXiv]
    Mathematical Proceedings of the Cambridge Philosophical Society, 157 (1), 1--11, 2014. 
  • Primitive Words, Free Factors and Measure Preservation. [journalarXiv]

  • Word Maps and Spectra of Random Graph LiftsWith Nati Linial[journalarXiv]
    Random Structures and Algorithms, 37 (1) 100--135, 2010. 
Preprints / Work in Progress:
  • Notes on the Cogrowth Formula: the Regular, Biregular and Irregular Cases
  • Spectrally Dominant Irreducible Representations of Symmetric Groups
  • Limit Distributions of words in Symmetric and Unitary Groups
