Today is the final day to view the exhibition “Tomashi Jackson: Across the Universe” at Tufts University Art Galleries. Deeply committed to social justice, the Cambridge-based Jackson creates vibrant prints, paintings, videos, textiles and sculptures that powerfully explore systemic inequities found throughout U.S. history. “Across the Universe” is the first exhibition to present the evolution of Jackson’s work over the past nine years, in which she fuses deep historical research with artistic strategies of color and layering to illuminate underrecognized patterns of activism, resistance, oppression and societal advances.
