My research focuses broadly on public administration, policy, and human resource management in the public sector. My research has been published in various academic journals including the Journal for Public Administration Research and Theory, Public Administration Review, Public Management Review, Behavioural Public Policy, Nature Scientific Reports, JAMA network open, and others. It has also been cited in policy documents (e.g., Joint Research Centre of the European Commission, OECD, World Bank, Danish Government Commission on Healthcare) and highlighted in both German and Danish media outlets including prime time TV news (e.g., ARD, ZDF) and national newspapers (e.g., Süddeutsche, Zeit, Berlingske, Jyllands-Posten).
I am particularly interested in the following topics:
Recruiting, selecting, and retaining the public workforce
The role of artificial intelligence (AI) in public policy and government
The motivation of citizens to contribute to public goods
Selected publications and working papers
