Thomas Gärtner joined the School of Computer Science in July 2015 as Professor of Data Science. Before that he was leading a research group jointly hosted by the University of Bonn and the Fraunhofer Institute for Intelligent Analysis and Information Systems. During that time he received an award from the Emmy Noether-Programme of the German Research Foundation (DFG). During his MSc studies at the University of Bristol and his PhD studies at the University of Bonn, Thomas focused on kernel functions for structured data in order to bridge the gap between theoretically sound machine learning algorithms and their real-world applications. His book, Kernels for Structured Data, was published in 2008. He has been an editor of the Machine Learning journal for several years and served as a senior programme committee member for several international flagship conferences on machine learning and data mining. Currently he is co-organizing the leading European conference on machine learning and data mining.
