I'm a post-doc jointly at the Bar-Ilan University and Weizmann Institute of Science. My hosts are Tali Kaufman and Irit Dinur. I got my PhD (Apr 2017) at the Einstein Institute of Mathematics of the Hebrew University of Jerusalem under the supervision of Alex Lubotzky.
I mostly do high dimensional combinatorics, and as well as some hyperbolic geometry.
Here is my CV in PDF, and my profile on ResearchGate. My e-mail is k.golubev@gmail.com.
