Jonathan Chaim Reus (b. US) is a performance artist and musician known for his usage of expanded digital instrumentation in live, theatrical and virtual (online) contexts.

He is a co-founder of the instrument inventors initiative [iii] in the Hague, and of Netherlands Coding Live [NL_CL], and a recipient of the W. J. Fulbright Fellowship for his work in research and development of new electronic music instruments at the former Studio for Electro-Instrumental Music [STEIM] in Amsterdam. In 2018, Reus was resident artist at the IEM in Graz for Algorithms that Matter [ALMAT], where he began to investigate the use of artificial voice in composition and performance contexts. This research continued into his work Wordless, a generative dialogue between two AI systems trained on a data set of voice recordings from Samuel Beckett and Morton Feldman, who read fragments of reviews of their oeuvres scraped from the internet and recombined into an imagined conversation.

Reus has received commissions as a composer and artist from Stedelijk Museum, Amsterdam, Slagwerk Den Haag, and Asko-Schönberg Ensemble, including composing original music and building on-stage robotic tape machine instruments for Brave New World 2.0, a nationally-touring ensemble production. Together with Sissel Marie Tonn he is one part of the artist duo Sensory Cartographies, whose wearable sound installation The Intimate Earthquake Archive, won honorable mention at Ars Electronica festival in 2020.

He is currently based in The Hague, and is studying towards a PhD in music composition at the University of Sussex in Brighton, UK.
