    Research Profile

    Researcher in European Law, in particular on the governance of administrative action in the Area of Freedom, Security and Justice and associated concurrent jurisdictions.  

    I am a Ph.D. candidate at the Amsterdam Centre for European Law and Governance, University of Amsterdam (ACELG) since January 2017. My PhD supervisors are Prof. Deirdre Curtin (Joint Chair of European Law and Politics, EUI) and Prof. Christina Eckes (director ACELG, UvA).  

    Summary statement

    Key words: concurrent jurisdictions, relationship between national and supranational authorities, liaison officers, information management.  

    The goal of this PhD research is to locate, identify and explore a novel type of administration in the EU: the in-between administration. The in-between administration is an executive that is deployed between two or more cooperating administrative authorities in order to – informally - carry out a range of administrative tasks. This new type of administration is of considerable flexibility in daily administrative practice and, consequently, will probably gain greater relevance in the future. Liaison officers serve as an illustration of the in-between administration.

    My research focuses on the deployment of officials (liaison officers): administrative agents who connect two or more administrative authorities of different jurisdictions. It is their objective to support their home administration in the enforcement of its laws. This support manifests itself in cooperation and coordination actions in (mainly) the area of security, justice and migration. Liaison officers have far-reaching administrative responsibilities and tasks such as the access to EU databases for policy implementation purposes in the field of police and judicial cooperation.

    Biographic note

    Prior to my Ph.D. position I studied European Law (LL.M. degree Leiden University in 2015) and Jurisprudence and Philosophy of Law (LL.M. degree Leiden University, 2016). In 2015 I interned at the Dutch Ministry of Foreign Affairs, EU law section, working on multiple EU court cases for the Kingdom of the Netherlands and on a range of research topics. In parallel to my master’s Jurisprudence and Philosophy of Law I worked as a research assistant to Professor Deirdre Curtin at ACELG. My work for Prof. Curtin focused on the supervision of data protection compliance by national and supranational authorities, a topic that yet reflects my Ph.D. to some extent.
