Thea Derks studied musicology at Amsterdam University, and specializes in contemporary music. She lectured on new music in Amsterdam Concertgebouw from 2005-2012, and has moderated pre-concert talks in Muziekgebouw aan ‘t IJ from its opening in 2005. There she also hosted several contemporary music courses. She advocates women composers, and published the much lauded biography Reinbert de Leeuw: mens of melodie in 2014.
In 2018 Derks published Een os op het dak: moderne muziek na 1900 in vogelvlucht, written for an interested but not versed audience.
