Hans Jahreiss, a German national, took up his duties on 1 July as Head of Administration at the European Domestic Agency (Fusion for Energy, F4E), bringing onboard a wealth of experience in management obtained in European and international agencies. As Head of Administration he will be responsible for driving forward F4E's procurement policy and managing the organization's administrative workload ranging from human resources, budget and finance, IT, logistics, legal matters and business intelligence.

"I am really looking forward to returning to work in a technical environment and to support this organization in its important mission. Having previously worked at the Max Planck Institute for Plasma Physics, coming to F4E feels like coming full circle," said Jahreiss. "I am very pleased to be part of the F4E team and be entrusted with such responsibility. ITER is a major international scientific project, in which Europe has an important role to play," he added.

Prior to joining F4E, Hans Jahreiss was most recently the Administrative Director of Eurojust, the European Union's judicial cooperation body. Before that, he was the Head of Administration at the European Organisation for Astronomical Research in the Southern Hemisphere (ESO) in Garching and Santiago de Chile, CEO and Managing Director at GSF—Forschungszentrum für Umwelt und Gesundheit (the National Research Centre for Environment and Health), and Head of Administration, Finance & Accounting, Contracts and Procurement at the Max Planck Institute for Plasmaphysics in Garching, Berlin, and Greifswald.

From 1993 to 1995, he worked as a Legal Advisor to the Head of Personnel at the European Organization for Nuclear Research, CERN, in Geneva, Switzerland; prior to that, he was Head of Facility Management and Internal Auditor at the Max Planck Institute.

Hans Jahreiss holds a Doctorate in Law and Assessor Juris and has started an MBA. He also obtained a Certificate in Philosophy, a Certificat en Droit Comparé, a Pupillage with Barrister-at-Law, a Baccalaureate in Accounting and Economy, and qualified in the Special Programme in English Law.

In addition to his mother tongue, Hans Jahreiss speaks English, French and some Spanish.
