Jörg Siekmann studied mathematics and physics in Göttingen and graduated in Computer Science at the University of Essex, England, where he also obtained his Ph.D. in 1976. Afterwards he worked as an assistant and associate professor in Karlsruhe and Kaiserslautern, Germany and headed several research groups in automated resoning and artificial intelligence. In 1991 he was appointed as a full professor at the department of computer science at the Saarland University and as a director at the at the German Research Centre for Artificial Intelligence (DFKI). His research groups worked on automated reasoning for mathematics, knowledge representation, e-Learning for mathematics, formal methods, multiagent systems, and IT-Security. Jörg Siekmann was the Chairman of the collaborative research center "Resource-adaptive Cognitive Processes" as well as Chairman of the Network of Excellence on Computational Logic (CoLogNet). He is Co-President of the International Federation on Computational Logic (IFCoLog). Currently he is a senior professor at Saarland University and he is the head of the Competence Center for e-Learning (CCeL) at the DFKI. His main research interests include artificial intelligence, automated reasoning, and e-Learning for mathematics. Jörg Siekmann has been active in founding three companies of which he is a share holder and he holds several patents.
