Gallagher works in paint, resin, inks and encaustic wax, often combining mediums to build dimensional paintings and sculptures. His color palette is expanding in more neon and acid tones, touching on the essence of life forms of the past or future.

Since 2011, Matthew Gallagher has been using self-developed methods combining physics, chemistry and mathematics to create art. Extending beyond various mediums and formats, his artwork is also entangled in his life, community practices, love for animals, and connection with people through performance and sound. Gallagher supports the work of experimental artists at his Cleveland studio and living space, R & D, which offers residencies for local, national and international artists.
