As a collaborative pianist, Ekaterina works extensively with vocal repertoire and has collaborated with internationally renowned singers including Vladimir Chernov, Vesselina Kasarova, Lisandro Abadie, and Birgit Steinberger, as well as with Virginia Genovese and Michael Hasslacher. In 2025, she participated in the Erasmus+ production of "Le Nozze di Figaro" in Castelfranco Veneto, Italy, as accompanist for the vocal class of bass-baritone Lisandro Abadie, further developing her expertise in operatic recitative. She has also worked as a collaborative pianist at the Belcanto Ossiach Academy and the International Vocal Artists Academy of Payerbach (IVAAP).

Her work in Lied has brought her to the Lied Academy in Žďár nad Sázavou, where she performed with soprano Virginia Genovese and received the Gustav Mahler Jihlava Music Festival Prize in 2025. The collaboration continued with a concert at the Birthplace of Gustav Mahler in Kaliště, Czech Republic, in 2026, where the programme combined vocal works with solo repertoire by Rachmaninoff and Liszt.

As a soloist, Ekaterina has performed works by composers including Bach, Brahms, Rachmaninoff and Liszt, and has appeared at concert venues and festivals in Austria and abroad. Her artistic development was marked from an early age by her orchestral debut at thirteen, performing Bach’s Concerto in D minor.

Alongside her concert activities, Ekaterina is dedicated to teaching and to the collaborative art of music-making. Her artistic focus lies at the intersection of solo piano, chamber music, Lied and opera, with an emphasis on attentive ensemble playing, stylistic versatility and close musical collaboration.
