Omer Mermelstein

I am currently a Van Vleck assistant professor at University of Wisconsin - Madison.

I used to be a PhD student in the Department of Mathematics at
Ben Gurion University of the Negev.

My thesis advisers were Dr. Assaf Hasson and Prof. Menachem Kojman.

### Research Interests

My main interest is in Model Theory and in particular ab initio Hrushovski constructions, their reducts and their associated combinatorial geometries.

My PhD dissertation is titled "Infinite and finite combinatorics around Hrushovski constructions" and you can find it here.

My M.Sc thesis is titled "Geometry preserving reducts of Hrushovski's non-collapsed construction" and is available upon request.
