Now again, we would like to take this opportunity to present some of the cur- rent topics, goals and methods of modern informatics. We introduce the work of our Institute and hope to arouse your interest, in the fascinating world of our science. The Max Planck Institute for Informatics aims to be a beacon of research in infor- matics. We aim to have impact in the following ways: First, through our scientifi c work, which we disseminate mainly through publications and books, but also in the form of software and Internet services. Second, through the training of young scien- tists, particularly during their doctoral and postdoctoral phases. We are educating future leaders in science and industry. Third, by assuming a formative role in our fi eld. We initiate and coordinate large research programs, and serve on important commit- tees. Fourth, by attracting talent from within and outside the country. About half of our research staff of over 180 scientists comes from abroad. Fifth, through the transfer of our results into industry. These transfers take place through collaborative projects, spin-offs, and people. Sixth, by building a world-class competence center for infor- matics in cooperation with our partners: Saarland University with its departments of Informatics and Computational Linguistics as well as its Center for Bioinformatics, the German Research Center for Artifi cial Intelligence, and the Max Planck Institute for Software Systems. We have continued to be very successful in all of these under- takings. Our success has become more visible through the erection of many new buildings around the Platz der Informatik on the Saarbrücken campus. In the next few months, the building for the Center of Internet Security, Privacy and Account- ability (CISPA) will be fi nished at the East corner of Stuhlsatzenhausweg. We are in the fi nal phase of the projects funded through the German Excellence Initiative – the Cluster of Excellence “Multimodal Computing and Interaction” and the “Saar- brücken Graduate School of Computer Science”. The recent evaluation of the Insti- tute by our Scientifi c Advisory Board has, once more, been very positive. This report is structured as follows: After an overview of the Institute and its depart- ments and research groups, we present the main areas of recent work. These topics span several departments and will also be the focus of our work in the next years. This part is followed by a section on our alumni and a brief overview of current events. The last part of the report contains a selection of recent scientifi c publications and a compact presentation of the Institute through key indicators. We wish you much enjoyment reading this report. Thomas Lengauer Managing Director 8 OVERVIEW The Max Planck Institute for Informatics, an Overview Information technology infl uences all aspects of our lives. Computer systems, hardware, soft- ware, and networks are among the most complex structures that have been constructed by man. Computational thinking is a new way of studying the universe. Basic research in informatics is needed to cope with this complexity, to lay the foundations for powerful computer systems, and to further develop computational thinking. 9 OVERVIEW Basic research in informatics has Goals Fifth, by transferring our results to indus- led to dramatic changes in our everyday The Max Planck Institute for Infor- try.
