About Me

I am a PhD student in the Hebrew University of Jerusalem supervised by Prof. Zlil Sela and Prof. Chloe Perin.

Prior to that I did my master's in the Hebrew University under the supervision of Prof. Chloe Perin.

My mathematical fields of interest include geometric group theory, more specifitly I am intrested in heirarcally hyperbolic groups (and more specificly mapping class groups).
