Mackie is Director and Curator of Education and Public Programs at Walker Art Center. Hailing from Sydney, Australia, Nisa came to the Walker after managing education and public programs at the Biennale of Sydney, where she organized discursive programs, performances, innovative learning initiatives, and large-scale artist projects and residencies across five separate venues. Her programs have featured a wide range of artists, including Douglas Gordon, Ane Hjort Guttu, Gabriel Lester, Randi and Katrine, AES+F, and Darius Miksys. Prior to the Biennale Nisa worked at a multi-disciplinary art center located in Sydney’s southwest, Casula Powerhouse Arts Center. Known for its best practices in community engagement and cultural capacity building, her two years at Casula were spent developing programs that reflected the local and global stories of its community. Most recently at the Walker, Nisa co-curated with Fionn Meade, e-flux and the University of Minnesota Press, Avant Museology a symposium examining the practices and sociological implications of contemporary museology.
