With the unfolding of the campus plan initiated in 2005, the Princeton campus is evolving and giving focus to key initiatives that deepen opportunities for cross-disciplinary work. For example, the natural sciences hub saw the opening in 2010 of the new Frick Chemistry Laboratory and the opening in 2013 of the Princeton Neuroscience Institute and Peretsman-Scully Hall, home to the Department of Psychology. New projects completed in 2016 include the Andlinger Center for Energy and the Environment, which connects researchers across disciplines to bring science and technology together in service to the planet; the Louis A. Simpson International Building, a shared space for Princeton's many international initiatives; and the Julis Romo Rabinowitz Building, home to the Department of Economics. The Lewis Center for the Arts, a major initiative that includes three new arts buildings and realizes the vision of extending the arts from edge to edge of campus at Princeton, opened in October 2017.
