Mary O’Neill gained her PhD from Oxford Brookes University in 2015. As part of her AHRC-funded Collaborative Doctoral Award with Penlee House Gallery & Museum, she curated ‘Model Citizens: Myths and Realities’, an exhibition of late-nineteenth-century Cornish painting, in summer 2014 in Penzance and wrote the accompanying book. She then contributed a chapter on Cornish art to the catalogue for an international exhibition of works from European artists' colonies at Hannover’s Landesmuseum.
She has recently collaborated on a publication to accompany an exhibition on the work of Henry Scott Tuke at Watts Gallery – Artists’ Village. Currently researching Irish art of the same period, she is also a tutor in Art History at Oxford University's Department for Continuing Education.
