Maybe it's the philosopher in me, but as an economist employed at the public administration department of the faculty of social sciences I am interested in combining theoretical and empirical insights of both disciplines, which is reflected in the current research I'm doing.

(Economic) co-evolution
I'm interested in applying tools from the economic field, known for its abstract modelling of the outside world, in order to understand parts of complex evolving systems. Public policy is connected to and with other systems, like the social or physical. In many respects these systems influence each other. By abstracting it is possible to focus on a limited amount of variables influencing the explananda. Is the economic discourse applicable to such particular discouse, and if so, what insights are created by applying it? To see more about what I'm doing on this subject look here.

Public safety policy
Contesting crime and ensuring safety has been on the national and local political agendas in the Netherlands for quite some time. This resulted in some major shifts in public safety policy; The Rotterdam public safety policy has been initiated mid 2001 in order to shift the focus from contingency oriented actions to programmatic oriented actions. However, not only in the Netherlands did a shift in public safety policy occur. Together with other researcher I do research in this policy field.

Association between games
When people interact they can play different games through time, that is, they can build up a history together. Players know how the other player played in the previous game. What if that previous game is a different game instead of the same game? The built up history still matters! The players can incorporate the actions, behaviour or play of previous games into their perception of the game at hand. I developed an approach to see how we can model and analyse people playing different games against each other instead of the same game: this approach is called the associative approach.

Micro-economics and welfare theory
Besides teaching on the subject of micro-economics and welfare theory I also like to explore some subjects to see where the concepts of micro-economics and welfare theory can be applied. This led together with Frank Dietz (red.) and Wim Heijman to the Dutch (text)book Toegepaste micro-economie (in English 'Applied micro-economics'). An internet site supports the book. See the teaching section also.
