October 13, 2011. Today I have successfully defended my PhD thesis. The slides of my introductory presentation are available here (in Dutch).
My research focuses primarily on the bibliometric mapping of scientific fields (various maps that I have constructed can be found here). I have written a PhD thesis on this topic. Another research interest that I have, which is somewhat separate from the rest of my work, is the construction and analysis of bibliometric performance indicators. In most of my research I am working closely together with Ludo Waltman.
