Hossein Nassajian Mojarrad

I am currently a postdoc in the Combinatorial Geometry group of Janos Pach. I did my PhD in the same group under the supervision of Prof. Janos Pach. I am interested in applications of algebraic, probabilistic, and combinatorial methods to various problems in discrete geometry and combinatorics.
