Raised in the Ruhr District (Ruhrgebiet) in Germany, Leonie relocated to Los Angeles as a teenager. She studied classical guitar at Los Angeles City College, and received a Bachelor Degree in Composition along with a Minor in Dance Performance at California State University Northridge in 2010.

She then moved to the Netherlands and earned her Master Degree in Composition at the Royal Conservatory of The Hague in 2013, where she studied with Peter Adriaansz and Calliope Tsoupaki. She then completed a one-year course at the Institute of Sonology, where she focused on Field Recording and the Spatialization of Sound. In 2016 she finished the fourth and last year of the Contemporary Music Through Non-Western Techniques Program at the Conservatory of Amsterdam with Rafael Reina as her principle teacher.

In 2016 alone her works have been performed in The Netherlands, Switzerland, Japan, and United States, and broadcast on radio stations in various countries, and her field recording soundscapes were chosen as winning entries of the Forum Wallis Ars Electronica Competition, as well as the GRIT Collaborative Competition.
She is active as a performer, composer, and sound artist, and teacher in various countries and places near and far, but essentially lives with her six-year-old son in the center of The Hague.
