After finishing music high school, she studied at the Bruckner-Konservatorium in Linz, Austria, majoring in Flute Performance. She continued her studies at the University of Music and Performing Arts in Vienna in Flute and Voice, covering both pedagogy and performance studies with Barbara Gisler-Haase (Flute), Annamaria Rott (Voice) and Walter Moore (Lied).

Another focus in her artistic work is Lied and oratory: Lied recitals, chamber music as well as oratory performances. She sang with ensembles such as the Ensemble Novantique, SWR Vokalensemble Stuttgart, CrossNova Ensemble and Company of Music, and has performed in concerts in Austria, Germany, Italy, Poland, Hungary, Luxemburg and Kyrgyzstan.
She can be heard on a CD production of Leonard Bernstein’s Mass with the NÖ Tonkünstler directed by Kristjan Järvi and the CD Dichterliebe Reloaded with the CrossNova Ensemble, released in 2013 by the national broadcasting network of Austria.
As a pedagogue she is teaching singing and flute at the Musikschule Meidling Vienna and has been mentoring students in teaching practice at the University of Music and Performing Arts in Vienna.
