Marielle was born in Manchester and studied at Manchester Metropolitan University before completing an MA at the Slade School of Fine Art. Recently she completed a practice-led PhD at the University of Leeds with full funding from WRoCAH. Currently she is living and working from her narrowboat whilst travelling around the waterways of England and Wales. Marielle holds a belief in the meaning-generating character of painting, and is passionate about art’s emotive power, and capacity to nourish change. She looks closely at the overlooked, the forgotten and the tiny things that make up the environment, and she cares deeply about the Earth and its inhabitants.

Marielle has exhibited widely as well as taking part in several international artist residency programmes. Recent exhibitions include: On Shaky Ground: Landscape, Paint and Change, 2023, Space at Design Gallery, Leeds; Genius Loci: Painting the Spirit of Place, 2022, APT gallery, London; Spectral Ground, 2021, The Woodshed Gallery, Folkestone (as part of Folkestone Triennial); Nightswimming 2018, Curated by LLE Gallery at Mission Gallery, Swansea; Squeeze, 2017, The Hive, London; Manchester Contemporary with LLE Gallery, 2016, Granada Studios, Manchester. In 2017 she was shortlisted for The John Ruskin Prize Exhibition, The Millenium Gallery, Sheffield and in 2016 she was shortlisted for Contemporary British Painting Prize
Riverside Gallery, London.
