Nicolas joined the Boston University Initiative on Cities, an urban leadership institute, in November 2017. He is co-author of the report "Cities Joining Ranks", which for the first time systematically reviews city policy networks in the US (incl. C40, 100RC, ICLEI USA) and develops clusters of cities based on membership overlaps. Drawing on the Menino Survey of Mayors, the only representative and scientifically rigorous study of mayoral priorities in the US, it also spotlights the motivations of mayors to join city networks.
Prior to coming to Boston, he completed his Master of Public Administration at the London School of Economics and Political Science. His graduate research focused on municipal collaboration in the face of climate adaptation challenges in the American Northeast and political barriers to solar PV in Florida.
