I am doing research in two different fields:
- Bibliometrics/Scientometrics. My research in this field focuses on two topics in particular:
- Bibliometric network analysis, in particular bibliometric mapping of science (see www.vosviewer.com).
- Bibliometric indicators of research performance.
- Economics. My economic research is concerned with the theoretical analysis of models of boundedly rational behavior. I have written a PhD thesis on this topic.
I am a member of the editorial boards of Journal of Informetrics and Scientometrics.
In most of my research I am working closely together with Nees Jan van Eck.
A list of my publications is available here.
