To celebrate Citizen Science Day, Brandeis University Library invites current students, faculty, staff, and alumni to have lunch and contribute to science! Please bring your laptop and lunch to the Gardner Jackson room in the Library on the Goldfarb Mezzanine. We will use the Zooniverse project website, and attendees can participate individually or as a group on a project of their own choosing. For consideration, the TreeVersity project is being run by the local Arnold Arboretum of Harvard University.
