About Me

Hi! I'm a postdoc at York University in Toronto, hosted by Paul Szeptycki.
I completed my Ph.D. in 2016 at UCLA under the supervision of Itay Neeman. After that I spent some time at Ben-Gurion University of the Negev with Menachem Kojman.
I am interested in set theory and its applications in general topology.
