Sofia Biryukova

Sofia Sergeyevna Biryukova (; born 19 July 1994) is a Russian figure skater. She is the 2013 Winter Universiade champion and 2011 Finlandia Trophy champion. Since Butsaeva was unable to attend, Svetlana Sokolovskaya stepped in to work with her at the event. On January 13, 2015, however, Biryukova stated she was unsure if she would continue pair skating or start coaching, feeling as though she hadn't made a lot of progress as a pair skater.

Deciding to end her pair skating career, Biryukova ended her partnership with Stepanov. Four months later, however, Biryukova was contacted by Nina Mozer, who convinced her to tryout with pair skater Andrei Filonov, who was looking for a partner. After a successful tryout, the pair decided to skate together and are coached by Dmitri Savin.

The pair made their skating debut at the 2016 Russian Figure Skating Championships, where they placed 7th.
