01 — Biography

About

I am an Assistant Professor at The Department of Mathematics and Statistics of Saint Louis University starting in August 2024.

From 2023–2024, I worked as a machine learning researcher at YerevaNN research lab and Yerevan State University (YSU).

From 2018–2022 I was a Postdoctoral Research Associate at the Department of Mathematics, The University of Arizona, affiliated with the Tripods Research group, working with Professor Stephen Kobourov.

I received my Ph.D. in Mathematics from the University of Minnesota under the supervision of Professor Gilad Lerman.
