She participated in master classes with Mietta Sighele and Veriano Luchetti in Riva del Garda, Italy.

[6] In 2014, she stepped into the role of Lucia at the last moment in Frédéric Bélier-Garcia's production at the Opéra de Marseille when Eglise Guttierez became ill.[7] Marková's performance was described as literally dazzling (littéralement éblouissante) and her interpretation throughout the performance was acclaimed for its depth of understanding (une Lucia qui ne cesse de sidérer par ce que l’interprète semble avoir compris et du rôle et d’elle-même).

A reviewer wrote that she was ideal for the role, noting the brilliance but also intimacy of her perfectly controlled voice, and her convincing acting.

[10] She made her Oper Frankfurt debut in the 2018/19 season as Elvira in Bellini's last opera I puritani,[1] staged by Vincent Boussard in cooperation with the Opéra Royal de Wallonie in Liège, alongside John Osborn.

[14][15] Her repertoire also includes Donna Anna in Mozart's Don Giovanni, the title role of Donizetti's Anna Bolena, Oscar in Verdi's Un ballo in maschera, Ines in Meyerbeer's L'Africaine, Micaëla in Bizet's Carmen, and the title role in Henri Sauguet's Les caprices de Marianne.
