I am Associate Professor in Public Policy and Policy Analysis at the Institute of Public Administration of Leiden University, where I currently chair the Politics and Governance section.

I am fascinated by how policy processes unfold, particularly in contexts of uncertainty and complexity. My research agenda explores these dynamics from multiple perspectives, including comparative policy analysis, policy design, the relationship between evidence and policy, policy evaluation, and policy innovation. I conduct both fundamental and applied research in these areas and have developed a particular methodological interest in qualitative evaluation methods. I have also built a substantial track record in advising national and international public sector organisations on the topics of my research.

I am serving in several national and international networks including IPPA, the International Public Policy Association (Executive Committee member); the International Research Group for Policy and Program Evaluation (INTEVAL); the International Network for Intergovernmental Science Advice (INGSA-Europe Advisory board member); the Flemish Evaluation Association (board member); the working group on policy evaluation of the Dutch Evaluation Association Vide (beroepsvereniging voor toezichthouders, inspecteurs, handhavers en evaluatoren); and COMPASSS COMPArative Methods for Systematic cross-caSe analysis (advisory board). I am also a founding member and former co-chair of the Permanent Study Group on ‘Policy Design and Evaluation’ of the European Group for Public Administration.

In addition, I am Associate Editor for Policy Design and Practice; and co-editor of the Policy Innovation section of the Journal of Comparative Policy Analysis: Research and Practice. I serve on the editorial boards of the American Journal of Evaluation; Evaluation and Program Planning; Public Policy Journal; Beleidsonderzoek Online; and Vlaams Tijdschrift voor Overheidsmanagement.  

Previously, I occupied positions as doctor-coordinator of the Policy Research Center Governmental Organisation and Decisive Government in Flanders (Steunpunt Bestuurlijke Organisatie Vlaanderen); researcher and lecturer at KU Leuven Public Governance Institute, and programme co-ordinator of the advanced Master of European Politics and Policies at KU Leuven Institute for International and European Policy. In 2014 I completed my PhD, entitled: “Policy evaluation activity unravelled. A configurational analysis of the incidence, number, locus and quality of policy evaluations in the Flemish public sector” (shortlisted for the Jaarprijs Politicologie, the annual prize for the best PhD in political science defended in the Netherlands or Flanders).
