Raquel Castro was born in Viseu, in 1976. She currently lives and works in Lisbon. In 2003, a video project about oral memory made her travel around Portugal and live in several regions of the country, collecting voices, images, sounds and children's drawings. She started to think about the way sound relates to the identity of a place, so she decided to start a research on sound studies. She directed the documentary Soundwalkers which was presented in Subtropics Festival in Miami and screened at various conferences of sound art and documentary film festivals. She collaborates sporadically with live visuals for theater and concerts. As a freelancer, she regularly directs and edits tv commercials, videoclips and other institutional works. As a teacher, she taught Direction and other disciplines at Universidade Lusíada, in Lisbon. She has a phd on Communication and Arts titled Sound, Space and Acoustic Identity. She created and curates the festival of sound art Lisboa Soa and the international symposium Invisible Places.
