This is the homepage of Philipp Schaer, Professor for Information Retrieval at Technische Hochschule Köln (University of Applied Sciences) and former postdoctoral researcher and team lead at GESIS – Leibniz Institute for the Social Sciences. I studied computer sciences at University of Koblenz where I received my master’s degree and Ph.D. (called Diplom-Informatiker and Dr. rer. nat. in Germany).

A lot of my research is located in the fields of digital libraries, information retrieval and the application of informetrics in the these fields. Feel free to have a look on my list of publications and recent talks to get an overview over my research topics.

A visual representation of what I am interested in can be seen in this Wordle from my Twitter profile*:
