Niekolaas Johannes Lekkerkerk (1988, NL) works as director and curator at RADIUS, center for contemporary art and ecology in Delft, which he founded in 2021. In 2012 he founded The Office for Curating. Previously, Lekkerkerk was director of the art space A Tale of A Tub in Rotterdam between 2019-2021; was the artistic director of Brussels-based platform POPPOSITIONS between 2016-2019; and was curatorial fellow at TENT in Rotterdam between 2015-2016.

Central to Lekkerkerk’s work as curator and writer are socio-political, theoretical and philosophical discourses revolving around climate and systemic change, environmental and ecosystems thought, social and climate justice. He particularly focuses on debates concerning the Anthropocene, modernism and natural sciences, regenerative ecologies, post-humanism, and the increasing entanglement between nature and culture, approached through the lenses of intersectional ecology and the philosophy of science.

Publications by Lekkerkerk include Worlding Ecologies: Art, Science and Activism Towards Climate Justice (Valiz, 2024), Bestiary of Corona Animals (Onomatopee, 2020), and The Standard Book of Noun-Verb Exhibition Grammar (Onomatopee, 2018).

In 2012 Lekkerkerk received the inaugural Demergon Curatorial Award, and in 2014 he was the beneficiary of the Akbank Sanat International Curator Competition.
