The recipient of numerous residencies, including the Robert Rauschenberg Foundation Residency (2016) Bemis Center for Contemporary Art (2014), and the Kohler Arts Industry (2012/2014), Harper creates installations that grapple with notions of loss, love, belonging and the ways we use objects to inform our notions of self. Harper’s work can be found in a number of notable collections including The Museum of Arts and Design (NYC), The John Michael Kohler Art Center, The Museum of Wisconsin Art, The National Gallery of Canada, the Frederick R. Weisman Art Foundation (Los Angeles), and the Art Gallery of Nova Scotia.
