Abstract: Dr. Ludo Waltman will provide an overview of his research on studying the fine-grained structure of science. He will discuss the clustering techniques that he has developed for identifying research topics at a highly detailed level of granularity. These techniques clusters scientific publications based on data from large-scale bibliometric databases. Recent algorithmic advances make it possible to identify many thousands of research topics throughout all fields of science in computing times of less than an hour. Dr. Waltman will also show practical examples illustrating how a fine-grained analysis of the structure of science allows us to address policy relevant questions, for instance related to the identification of emerging research topics and the comparison of the research profiles of universities.

Speaker Bio: Ludo Waltman is deputy director and senior researcher at the Centre for Science and Technology Studies (CWTS) at Leiden University in the Netherlands. Ludo leads the Quantitative Science Studies (QSS) research group. His research interests focus on methodological topics in the fields of bibliometrics and scientometrics, in particular the analysis and visualization of bibliometric networks and the development of scientometric indicators. Lude is one of the developers of VOSviewer, a popular software tool for visualizing bibliometric networks (www.vosviewer.com). Ludo also serves as Editor-in-Chief of Journal of Informetrics.

All Drexel faculty, professional staff, and students are welcome to attend this free event. Pizza/salads will be served.
