After studying singing pedagogy at the Mozarteum University in Salzburg, he worked for several years as a voice coach (including the Salzburg Cathedral Boys' Choir, the Salzburg State Music School/Musikum Salzburg and the Tölzer Boys' Choir). Shaped by a one-year research stay at the Center for Computer Research in Music and Acoustics at Stanford University, he decided to devote himself full-time to voice research. After completing his doctorate in biophysics, he worked at the Bioacoustics Laboratory, Department of Cognitive Biology, University of Vienna, and as a post-doctoral researcher at the Voice Research Laboratory, Department of Biophysics, University of Olomouc. Since 2016 he has been working on the project "Comparative Biomechanics of Mammalian Sound Production", funded by an APART grant from the Austrian Academy of Sciences. Christian Herbst is a member of the advisory board of the Voice Foundation and an editorial board member of the Journal of Voice and of Logopedics, Phoniatrics and Vocology. As part of the investigation of physiological processes in the singer's larynx, he has published multiple award-winning works in international journals. As head of the bioacoustics laboratory at the Department of Cognitive Biology at the At the University of Vienna, he conducts studies on the physics of voice production in mammals, among other things. In this context, he published a study on the physical mechanism of voice production in elephants in the renowned Science Journal.
