She is the author of Stereophonica: Sound and Space in Science, Technology, and the Arts (MIT Press 2021) and the forthcoming The Trembling City, which investigates cities as in relation to sound and vibrational force, particularly in the contexts of war, genocide, and mass violence. Ouzounian leads the project Sonorous Cities at the University of Oxford, where she is associate professor of music. She hosts the conversation series Countersonics: Radical Sonic Imaginaries, which asks how sonic practices can operate as modes of resistance and repair in times of conflict and crisis.
