I am a mathematician working in the field of Extremal and Probabilistics Combinatorics and Graph Theory.
I joined Emory university Mathematics department as an Assistant Professor in Fall 2021. Prior to that I was a Marie Curie Global Fellow at London School of Economics. My host was Julia Boettcher. During 2019-2020 academic year I was a visiting scholar at University of Illinois at Chicago, hosted by Dhruv Mubayi. Prior to this position, I was a postdoctorate researcher at University of Oxford during 2016-2019 academic years. I was supervised by Professor Peter Keevash. During this time, thanks to Tom Sanders, I was also a stipendiary lecturer in Mathematics at St. Hugh’s college for two academic years - 2016-2017 and 2018-2019. I am thankful to all my hosts at these universities for their time, generosity and support.
I received Ph.D in Computer Science from from McGill University, Canada in 2016, under the supervision of Sergey Norin and co-supervision of Hamed Hatami. I am myself fortunate to supervise the following Ph.D students:
Bryce Frederickson (graduating May 2026), on job market!
Sean Longbrake (graduating May 2027)
If you are interested in working with me, don't hesitate to send me an e-mail.
I obtained my undergraduate (2005-2009) and masters degrees ( 2009-2011) from Applied Mathematics and Informatics department at Yerevan State University, Armenia.
