I am a postdoctoral researcher at the Department of Mathematics at Ben-Gurion university of the Negev. Before that, I was a Minerva postdoctoral researcher at BIREP – Representations of finite dimensional algebras at Bielefeld research group. My host was Prof. Henning Krause. Before that I was a postdoctoral researcher at the Department of Mathematics at the University of Antwerp, hosted  by Prof. Wendy Lowen. Before that I was a postdoctoral researcher at the Weizmann institute. I graduated in 2013 from Ben-Gurion university of the Negev. My Phd advisor was Prof. Amnon Yekutieli.
