Nuno Fonseca is an associate researcher at the Nova Institute of Philosophy (Ifilnova), where he coordinated the Aesthetics and Philosophy of Art research group between 2019 and 2025, and at the Centre for Studies in Music (CESEM), where he is a member of the Contemporary Music research group. His research focuses on aesthetic concepts and values, particularly within the context of everyday urban experience, as well as the ontological, epistemological, and cultural aspects of sound experience, especially in relation to what is now called “sound arts”. Since the 1990s, he has experimented with the medium of sound, namely by making radio programmes for RUC and, more recently, Antena 2 (Cóclea – O Labirinto da Escuta, 2022). He has also contributed to sound design for theatre and performance works.
