jaeger2012Gerhard Jäger is Professor of General Linguistics at the University of Tübingen. His current research interests are on the empirical study of language evolution, drawing ideas and methods from historical linguistics and typology, natural language processing, evolutionary biology, and bioinformatics. Trained at the University of Leipzig and the Humboldt University in Berlin, Prof. Jäger has been a visiting researcher at several international universities, including the University of Pennsylvania (USA), University of Utrecht (Netherlands), and Stanford University (USA). In addition, he has completed fellowships at the Swedish Collegium for Advanced Study and the Netherlands Institute for Advanced Study. Prof. Jäger was awarded an Advanced Grant from the European Research Council (ERC) in 2013 for the five-year project “Language Evolution: The Empirical Turn” (EVOLAEMP), where he is the Principal Investigator. With Prof. Katerina Harvati, he currently directs the DFG Center for Advanced Studies “Words, Bones, Genes, Tools: Tracking linguistic, cultural, and biological trajectories of the human past.” Prof. Jäger has co-organized several international workshops, symposia, and conferences, including the Workshop on historical and empirical evolutionary Linguistics (WheeL), the 26th European Summer School in Logic, Language, and Information (ESSLI 2014), and the 6th Conference on Quantitative Investigations in Theoretical Linguistics (QITL-6). Prof. Jäger’s work has been published in international journals, among them the Proceedings of the National Academy of Sciences (PNAS), Philosophical Transactions of the Royal Society B, Journal of Theoretical Biology, and Language Dynamics and Change.
