Ulrich Sieber is a director at the Max Planck Institute for Foreign and International Criminal Law in Freiburg/Germany and an honorary professor and faculty member at the law faculties of the University of Freiburg and the University of Munich. He is an advisory professor at the law departments of Renmin University of China, the Beijing Normal University/China, and the Wuhan University/China.


Academic Background:

Prof. Sieber launched his academic career at the University of Freiburg, where he was a researcher and academic staff member from 1973 to 1987. In 1977, he was awarded a doctorate for his dissertation on computer crime and criminal law (Computerkriminalität und Strafrecht) and completed the bar exam. From 1978 to 1987, he also worked as an attorney specializing in computer law. Under the supervision of Prof. Dr. Klaus Tiedemann, he earned a post-doctoral lecturing qualification at the University of Freiburg in 1987 with a Habilitation on the relationship between substantive criminal law and criminal procedure. In the same year, he accepted a position as professor of criminal law, criminal procedure, and information law at the University of Bayreuth. In 1991, Prof. Sieber became professor of criminal law, criminal procedure, information law, and legal informatics at the University of Würzburg, where he was dean of the law faculty from 1997 to 1998. He declined an offer of professorship for legal informatics from the University of Münster in 1994. Also in 1994, he was a visiting professor at the University of Tokyo. In April 2000, he accepted an appointment to succeed Prof. Dr. Claus Roxin at the University of Munich.

In October 2003, Prof. Sieber was appointed director at the Max Planck Institute for Foreign and International Criminal Law in Freiburg, succeeding Prof. Dr. Hans-Heinrich Jescheck and Prof. Dr. Albin Eser. Since 2003, he has also been an honorary professor and the scientific director of the Center for Information Technology in Law at the law faculty of the University of Munich. He has been an honorary professor at the law faculty of the University of Freiburg since 2004. As a faculty member, he is authorized to supervise doctoral and post-doctoral candidates at both universities. He is also the initiator and spokesperson of the International Max Planck Research School for Comparative Criminal Law (IMPRS-CC), a cooperative venture of the Max Planck Institute in Freiburg and the law faculty of the University of Freiburg.

National and International Consulting:

In addition to his academic work, Prof. Sieber continues to be active as an expert consultant and advisor, especially in the areas of computer law, economic criminal law, and international criminal law. In this capacity, he has served as a special advisor to two EC Commissioners with his expertise on issues of computer law and EC fraud. He has also served on the legal committee and several enquiry commissions of the German Parliament and has advised the German Federal Constitutional Court, the German Ministry of Justice, the German Ministry of Education, Science, Research, and Technology, and the German Federal Police Office. He has advised the Council of Ministers and the Parliamentary Assembly of the Council of Europe, the European Commission, the Research Ministers of the G-8 nations (Carnegie Group), the OECD, the United Nations, and the International Chamber of Commerce in Paris. He has also been a consultant to the U.S. Senate, the Canadian Ministry of Justice, and the National Police Agency of Japan, as well as an expert witness for the International Criminal Tribunal for the former Yugoslavia (ICTY).

Memberships and Editorships:


Prof. Sieber is president and a founding member of the German Association for European Criminal Law (Deutsche Vereinigung für Europäisches Strafrecht e.V.), vice president of the Association Internationale pour la Défense Sociale, a member of the board of directors of the International Association of Penal Law (AIDP) and vice president of its German section, a member of the International Academy of Comparative Law, a member of the board of the European Center for European Law at the University of Würzburg, and an honorary member of the Japanese Association of Criminal Law Professors.

He is editor of the Strafrechtliche Forschungsberichte [Reports on Research in Criminal Law] of the Max Planck Institute for Foreign and International Criminal Law in Freiburg, editor-in-chief of the online publication eucrim, and editor of the European series ius informationis and ius criminale. He is also co-editor of the periodical Multimedia und Recht, the compendium Multimedia-Recht, the European series ius europaeum, the foreign press review of the Zeitschrift für die gesamte Strafrechtswissenschaft (ZStW), and the interdisciplinary research series of the Max Planck Institute for Foreign and International Criminal Law that includes interdisciplinary reports on research in criminal law and criminology as well as a collection of foreign criminal laws in German translation.

In addition, he is a member of the international scientific committee of Revue de science criminelle et de droit pénal comparé (RSC), the correspondent panel of The Computer Law and Security Report, the editorial board of International Criminal Law Review, and the advisory board of Money Laundering Control. He also serves on the advisory councils of the journals Computer und Recht, Multimedia und RechtRevista Penal, and the Greek online publication Recht und Neue Technologien.

Current Research Program:


The research program of Prof. Sieber at the Max Planck Institute for Foreign and International Criminal Law in Freiburg is closely attuned to current changes in crime, criminal law, and criminal policy in today's global information and risk society. New challenges to criminal law emerge with these changes. Contributors to the urgency of these challenges include the growing transnationality of crime, the increasing threat level, and the high degree of complexity. These factors are especially apparent in the areas of terrorism, organized crime, economic crime, and cybercrime – all focuses of the research program.

These developments have pushed traditional criminal law to its territorial and functional limits as regards the protection of society and the guarantees of individual freedoms. New questions arise, for example, as to the conceptual design of a transnationally effective criminal law, the role of criminal law in the context of the emerging preventive orientation towards security interests, and alternative systems of social control.

Against this background, the research program of the Department of Criminal Law at the Max Planck Institute for Foreign and International Criminal Law pursues three related, progressive research goals: (1) the analysis of empirical changes in delinquency and security risks in a society shaped by globalization, technological advances, and economic development; (2) the analysis and critical evaluation of the corresponding normative changes in criminal law and practice; and (3) the development of viable responses to present-day and future criminal policy issues spawned by these changes.

The primary research methods used to achieve these aims include legal doctrine, international criminal law science, and comparative criminal law as well as methods of empirical social research and the inclusion of fundamental questions of legal theory, international law, European law, and human rights. In this way, a frame of reference for criminal justice in multi-level systems can be determined.
