Mari Ohno is a Japanese sound artist and researcher, based in Tokyo.

She composes with matter to explore the boundary between the natural and the artificial, which is becoming increasingly blurred around us. She reinterprets natural elements and processes from post-anthropocentric view and harnesses the unexplored potentials of matter for her sonic and visual expression. Her practice represents the interdisciplinary explorations of co-composition between natural and artificial matter as otherworldly phenomena, by integrating current theories and methodologies in art, design, science, and philosophy.

Her works have been exhibited and performed in public, including the Museum of Contemporary Art Tokyo, Science Gallery London, MU, SARC Belfast, EMPAC New York, Centro Cultural FIESP Sao Paulo and Hong Kong Arts Centre. She has been awarded Sound and Music Embedded with Cafe OTO in the UK, the Jury Selection of Japan Media Arts Festival, and others.

She graduated with a PhD from Goldsmiths, University of London, following the completion of two MAs from Goldsmiths, University of London and Tokyo University of the Arts.
