General Information:

I am a Ph.D. student at Luddy School of Informatics, Computing, and Engineering; Indiana University, Bloomington working under the supervision of Qin Zhang and Cenk Sahinalp.

Before I come here, I graduated from St. Petersburg Academic University with an MSc degree under the supervision of Fedor Fomin and Alexander Kulikov. I graduated from St. Petersburg State University with BSc degree in Math.

I am currently supported by the following grants NSF CCF-1844234 and NSF CCF-2006591.

Misc:

Sometimes I participate in programming contests (meta profile).
