Through performance, text, audio and video, Martha's work straddles the borders of the private and the public, the ordinary and the epic. By abstracting personal documents such as correspondence, calendars, diaries and to-do lists through narration her work investigates subjective feeling and experience as the micro product by which societal normatives and complexities can be laid bare. Often taking place outside of designated presentation spaces such as through the intercom of her apartment, her work has been part of group shows and programs at De Oude Kerk, Amsterdam, De Vishal, Haarlem Can Felipa, Barcelona and The Lumberyard, Marfa, Texas, amongst others.

Her interest in the private domain, the epistolary form and offsite presentations are also at the base of her curatorial projects. She is the founder of Dear, a publishing series which connects poets, writers and artists to an audience by the means of the written letter distributed by post. Together with Isabelle Sully she directs Playbill, an event-based project focused on experimental text - and language based artistic practices, currently hosted by Torpedo Theater in Amsterdam.
