O’Dwyer is a multidisciplinary artist whose work is informed by both the conceptual concerns of sound art and traditional composition techniques, embracing the broader aesthetics of sound and its relationship to environment.

She has created works for large-scale and intimate settings that allow for both planned and unplanned compositions to co-exist in live situ. Recent works include 'Poems for Daedalus’ , a series of site-specific performances developed in Athens 2018; the book 'Poems for play', a collection of scores for a Jesuit monastery; 'Accompaniment for Captives’ ,  a performance for two fishing boats; 'Performance for Live Stream' (Cafe OTO, 2021), an audio-visual work; 'Song of Place' (2022) a street opera staged in Bristol suburbia and ‘Sing in the Dark’ ( 2024 ) a live vocal performance for acousmonium.
