Prof. Dr. Stefan Wrobel

Institute Director

Prof. Dr. Stefan Wrobel is Professor of Computer Science at University of Bonn and Director of the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS. He studied computer science and artificial intelligence in Bonn and Atlanta, Georgia/USA (M.S., Georgia Institute of Technology) and obtained his PhD at the University of Dortmund. After holding positions in Berlin and Sankt Augustin he was appointed Professor of Practical Computer Science at Magdeburg University, before taking up his current position in 2002. In addition, since 2014 he is one of the directors of the Bonn-Aachen International Center for Information Technology (b-it).

Professor Wrobel’s work is focused on questions of the digital revolution, in particular intelligent algorithms and systems for the large-scale analysis of data and the influence of Big Data/Smart Data on the use of information in companies and society. He is the author of a large number of publications on data mining and machine learning, is on the Editorial Board of several leading academic journals in his field, and is an elected founding member of the “International Machine Learning Society”. As Speaker of the »Fraunhofer Big Data Alliance«, vice-speaker of the »Fraunhofer Information and Communication Technology Group« and speaker of the »Fachgruppe Knowledge Discovery, Data Mining und Maschinelles Lernen«, a Special Interest Group of the German Computer Science Society, he is engaged nationally and internationally in pushing forward the benefits of digitization.
