Alice Eldridge’s background in music, psychology, evolutionary and adaptive systems and informatics underpins creative and empirical interdisciplinary research in sonic (complex) systems at the interstices of music, technology and ecology. This includes improvisation, composition, field recording, instrument building and computational analysis of natural acoustic environments within the emerging field of ecoacoustics, braided with ideas and methods from adaptive and complex systems. Current and recently funded projects include: development of novel acoustic methods for ecological assessment and wilderness mapping in terrestrial and marine environments; participatory design of networked notation software to support ensemble music making; and exploring feedback as a design principle and musical aesthetic through developing new feedback musical instruments. Alice Eldridge is Director of the Sussex Humanities Lab. She has appeared on BBC TV Spring Watch and BBC radio 4 Costing the Earth as a soundscape ecologist.
