Sommers expanded the Daniels Faculty, adding five new programs including a renewed undergraduate program in Architectural Studies, a PhD in Architecture, Landscape, and Design, and amalgamating University of Toronto's programs in Art/Visual Studies and Forestry.^[7] Sommer co-curated, with Pillow Culture NYC, the inaugural exhibition at the Architecture and Design Gallery, New Circadia (Adventures in mental spelunking)^[8] based on ongoing research on the democratic potential of collective spaces of idling, dream sharing and rest.^[9]
