About

I am a PhD student at the Mathematics Department at the Weizmann Institute of Science, where I am very fortunate to be advised by Prof. Itai Benjamini. My research is supported by the ADAMS Fellowship.

I am intrigued by extremal questions on discrete structures such as graphs and simplicial complexes, and their relation to the design and analysis of algorithms. My interests span Algorithms, Combinatorics, and High Dimensional Combinatorics and Geometry.
