Peter O’Doherty (1973) is an Irish composer, sound artist and new music curator. His work often deals with memory, time, language and the relationship between text, code and gesture.

His work falls into several categories: scores (often constructed with the aid of computational algorithms, to be interpreted by human performers); performance (using voice, objects and electronics); electroacoustic music (composed using software and diffused in performance using multi-channel audio playback systems); and texts (constructed and assembled with the assistance of algorithms, performed verbally, or presented in written form).

His music and sound works have been performed in Ireland, Scotland, the former Yugoslavia, Finland and The Netherlands.

He received a BMus (Hons.) from the University of Edinburgh and an MMus from Ulster University. He is artistic director of Northern Lights Project, a Derry-based organisation that promotes, produces and commissions new music.
