Sixty-Five Years of European Governance (co-ed 2016) eleven articles demonstrate the creative and often fragile solutions found to address the challenges facing Europe by analyzing transformations in European governance.

Multilevel Citizenship (ed 2013) disputes the dominant narrative of citizenship as a homogeneous status bestowed only by nation-states; it considers overlapping jurisdictions, sub- or supranational citizenships, and shared governance.
