Katja was born in Moscow and began her musical education at the prestigious Gnessin Music School at the age of five, which led to her winning several international competitions during her school years. Her exceptional talent was affirmed by grant awards from the New Names Foundation as well as the distinguished Vladimir Spivakov Trust, who then invited her on an extensive tour throughout Siberia playing numerous times as the soloist with a symphony orchestra.
She continued her studies at the Tchaikovsky Conservatory in Moscow from 1999 to 2005 – her tutors including the flutist Olga Ivusheikova, the pianist Alexei Lubimov, and the cellist Natalia Gutman.
From 2001 to 2008, Katja studied in the early music department at the Royal Conservatory, The Hague. She finished her education with a master's degree under the guidance of the traverso player, Professor Barthold Kuijken and also had lessons with Kate Clark and Wilbert Hazelzet.
