He served as general editor of the eleven-volume series of Oxford Handbooks of Political Science. His own work straddles democratic theory (e.g. Reflective Democracy, OUP 2003), empirical welfare-state studies (e.g., The Real Worlds of Welfare Capitalism, CUP 1999; Discretionary Time, CUP 2008) and theoretical reflections on public policy (e.g., Social Welfare as an Individual Responsibility, CUP 1998; What's Wrong with Terrorism? Polity 2006). Thomas Schillemans is a public administration scholar. He received his PhD with honors in 2007 for his thesis on Horizontal Accountability in the Shadow of Hierarchy. His working experience includes seven years at the council for social development, an advisory body of the Dutch government. His research aims to make sense of dispersed practices of governance through empirical studies that examine the interactions of executive agencies, regulators and nonprofit organizations with relevant stakeholders: clients, professional peers and the newsmedia. Public accountability is a key concept in his work. He is assistant professor at the Utrecht University School of Governance.
