Guest curator Martina Tanga will lead a tour of the Tufts University Art Galleries exhibit “Stack, Layer, and Arrange,” a retrospective of Julie S. Graham (1947–2018), Boston-based painter and beloved instructor at the School of the Museum of Fine Arts at Tufts. “Stack, Layer, and Arrange” presents paintings, drawings, sculptures and photographs spanning Graham’s career, reflecting an artist consistently inspired by architecture and the incidental alignment of shapes in the world. Tanga is a curatorial research and interpretation associate at the Museum of Fine Arts, Boston. The exhibit is on display in the Aidekman Arts Center through Sunday, September 29.
