Currently I am a postdoctoral fellow in the mathematics department at the Ben Gurion University of the Negev in Be'er Sheva, under the supervisions of Dr. Assaf Hasson and Dr. Moshe Kamensky.
During October 2017 - September 2018 I was a postdoctoral fellow in the mathematics department at the Hebrew University of Jerusalem, under the supervision of Prof. Saharon Shelah.
I did my Ph.D. student at the mathematics department at the Hebrew University of Jerusalem, under the supervision of Prof. Ehud Hrushovski. I received my M.Sc. in mathematics from the Hebrew University of Jerusalem, working on Algebraic Semigroups under the supervision of Prof. Yakov Varshavski.
I'm specifically interested in Model Theory and its connections with Algebra and Algebraic Geometry.

## Research

I am mainly interested in Model Theory and its connections to other parts of mathematics, especially Algebra and Geometry.
