David was born in 1987 under the surname Teresa Carballo,  and was raised in a small town situated in the heart of Germany. In 2004, David started his career as musician, composer, and audio engineer followed by numerous concerts and studio recordings. In addition to his work as a musician, he completed his apprenticeship as a nurse in 2009 and worked on intensive care units in various hospitals between 2010 and 2018. David has dedicated himself to the research fields of musicology and media studies since 2015--making him the first in his working-class family with a migration background to study at a university. In 2018, he graduated with a bachelor's degree in musicology at the Humboldt University of Berlin (Germany), followed by a master's degree in media studies with summa cum laude at the same institution in 2021. Despite battling dyslexia, David was awarded the Humboldt-Scholarship (as part of the Germany Scholarship program) in 2020 for outstanding performance. Since 2022, he is a PhD candidate at the University of Western Australia (Conservatorium of Music) investigating new hearing aesthetics based on the biotechnology cochlear implant. Alongside his academic career, he invented the Theremin for the Deaf, the first musical instrument to produce sound without acoustics. From 2016-2019, David worked for the broadcast show Fritz Unsigned as a social media manager and as a freelance Radio-Journalist. He also designed the app Tour It Yourself, which enables musicians to book and manage concerts independently. Between 2020 and 2021, David was a co-organizer of TEDxHUBerlin, an independent and self-organized format of the worldwide renowned lecture and knowledge platform TED. Finally--and the most importantly--David has been the proud father of a spirited and hilarious daughter since 2014.
