About Me

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

Before that, I've completed my master's degree at the Hebrew University under the supervision of Prof. Chloé Perin.

My mathematical fields of interest include geometric group theory; more specifically, I am interested in hierarchically hyperbolic groups (and especially mapping class groups).
