Biography
My supervisor was Hillel Furstenberg. My thesis "Ramsey properties of subsets of N" was defended in 2007, at Hebrew University of Jerusalem, Israel.
Afterwards, for three years I was Zassenhaus
Assistant Professor at Ohio State University
and for another three years I was Van Vleck Assistant
Professor at UWMadison .
