Oona's work focuses on the extinction or the nearing extinct. Among the associated consequences, extinction places species literally and metaphorically out of sight. The experience of barriers and boundaries, physical, visual and emblematic, and the asymmetries of experience reflected in her work, are part of the fascination with that which is out of sight, but which remains potent in the memory and the imagination.
Recent works include research and print/sculpture installation at Space Bom Suwon Museum of Contemporary Art Korea and new works for a commissioned work for Trinity College Dublin on the theme of Myrmecophytism (plants and animals or insects symbiotic relationships).
She has over 25 years experience working as a professional artist and managed a fine art print workshop, Clo Ceardlann na gCnoc, in the Donegal Gaeltacht in the North West of Ireland until 2014. She represented Ireland at the Onsaemiro Project, a research and exhibition in the Joint Security Area between North and South Korea in 2019 and the Sao Paulo Biennale event 'Beyond the Horizon' in 2018.
