Julia Demann was born in Cologne—and stayed there. After studying German in Bonn and completing various journalistic internships, it became clear: she wanted to become a journalist. Specifically, a science journalist. That's why she returned to Cologne, studied biology, and began working as a freelance writer for a health magazine in public broadcasting. She then achieved her goal—working at Quarks. For almost five years now, she has been working there as a freelance writer for radio and podcasts, as well as a presenter and writer for the Quarks YouTube channel. Additionally, she hosts the podcast "Die Ernährungsdocs" on NDR. Her areas of expertise include sexuality, nutrition, and infectious diseases.
