Her work explores stories about land, mythology, ritual, thresholds and imprints, the individual's relationship to landscape, and a land’s ability to evoke memory whether real or imagined. Photography is her primary medium however drawings, found images, printmaking, video, and writing are also incorporated into her practice. Much of her inspiration is grounded in literature.
Her first book, a collection of photographs and drawings made in Iceland between 2011-2013 entitled 'As if it should have been a quarry' was released in late 2013 with Damiani publishers and includes an introductory essay by Eduardo Cadava. As if it should have been a quarry was recently shown as a solo exhibition at La Galerie Particulière in Paris and Brussels. Most recently this work was featured as part of a group exhibition entitled "Fragments" at La Frontiera gallery in Paris.
