His research concerns include symmetric spaces of arithmetic groups and their combinatoric, geometric, and topological structure.
The prize recognises his fundamental paper in the Journal of Topology and Analysis, in which he extends both the combinatorics and automorphic form theory to generalise the construction of Mikhail Gromov and others on expander graphs.
His fundamental work will have major implications even outside mathematics, extending into theoretical computer science, according to the citation.
[1][2] He subsequently returned to the Hebrew University of Jerusalem as a senior lecturer in the Einstein Institute of Mathematics.
