Defne Ayas

Defne Ayas (born 1976) is a curator, lecturer, educator, and editor in the field of contemporary art and its institutions. She is born in Germany, grew up in Istanbul, and is now based in Eindhoven. Since September 2025 she is director of the Van Abbemuseum in Eindhoven.

Ayas directed, cofounded, curated, and advised several art institutes, initiatives, and exhibition platforms across the globe, including in the United States, Netherlands, China and Hong Kong, South Korea, Russia, Lithuania, and Italy. Exploring art's role within social and political processes, Ayas is best known for conceiving inventive exhibition and biennale formats within diverse geographies, in each instance composing interdisciplinary frameworks that provide historical anchoring and engagement with local conditions. Working between Berlin and New York since 2018, she currently serves as Senior Program Advisor and Curator at Large at Performa. Until June 2021, Ayas was the artistic director of the 2021 Gwangju Biennale, together with Natasha Ginwala.

Defne Ayas was the director of the Witte de With Center for Contemporary Art in Rotterdam (2012-2017). Towards the end of her tenure in 2017, she announced that the institution had to change its name to dissociate itself from its namesake, the Dutch naval officer Witte Corneliszoon de With. The institution's decision to change its name was immediately politicized, causing controversy in the Netherlands. The decision for a name change was triggered by an Open Letter to Witte de With published on 14 June 2017 by Egbert Alejandro Martina, Ramona Sno, Hodan Warsame, Patricia Schor, Amal Alhaag, and Maria Guggenbichler, and the debates that followed.
