The Office for International Relations

Head of International Relations
Felicitas Pauss

Prof. Dr. Felicitas Pauss is Head of International Relations at CERN, Geneva, Switzerland and Professor for Experimental Particle Physics at the Swiss Federal Institute of Technology Zurich (ETH Zurich), Switzerland. Felicitas Pauss received her PhD degree in Theoretical Physics and Mathematics at the University of Graz (Austria) in 1976. In 1978 she started to work as a postdoc at the Max-Planck Institute in Munich (Germany) where she changed to the field of Experimental Particle Physics. She continued her research at Cornell University (USA) and CERN before she was elected professor at ETH Zurich in 1993. She joined the CMS collaboration in 1994, and has contributed to the design and construction of the CMS experiment, one of the two large detectors at CERN’s Large Hadron Collider. She has been a member of the Management Board, and has fulfilled other important management duties within CMS. From 1997 till 2007 she was the director of the Institute for Particle Physics of ETH Zurich. Since January 2009 she is in charge of coordinating CERN’s international relations.

Besides lecturing at the undergraduate and graduate level at ETH Zurich, her research activities concentrate on two main research fields: Particle Physics at the High-Energy Frontier and Astroparticle Physics, addressing fundamental open questions about the structure of the Universe and the underlying mechanisms that govern its evolution. She has published more than 450 scientific papers and gave more than 260 talks at international conferences, colloquia and seminars as well as presentations for government officials, funding agencies and general public.

Felicitas Pauss has always pursued a strong interest in shaping the future of particle physics. She participated in various working groups to evaluate the physics potential of new accelerator projects in Europe and in the US and has served and still serves on numerous international scientific advisory boards. She has received the "Grand Decoration of Honour" of the Federal Province of Styria (Austria), the "Cross of Honour for Science and Art, First Class" of the Republic of Austria and is member of the German Academy of Science Leopoldina.


Non Member States Advisors (Countries/Regions)
Patrick Fassnacht
Middle East, North Africa

Patrick Fassnacht started in Experimental Nuclear and Particle Physics at the University of Strasbourg (France) in 1979. From Nuclear Physics he moved to Intermediate Energy Physics participating to various experiments in the domain of “coherent” pion production and searches of multibaryonic states at the CERN SC and at SATURNE (Saclay/France). In 1984 he got his PhD diploma of “Docteur Es-Sciences”. When joining the CPPM at Marseille he moved to High Energy Physics joining the CPLear collaboration (focus on CP violation in the 3pi channel) and finally the ATLAS experiment. To the latter he contributed as Test Beam coordinator and later for six years as Technical Coordinator of the ATLAS Liquid Argon Calorimeter system. He was responsible for getting the calorimeters assembled, integrated into the cryostats and commissioned. From April 2004 onwards, for a period of more than six years, he was acting as CERN ATLAS Team leader. During that period he had interactions with the numerous ATLAS Users coming to CERN; at that time he started to establish strong collaboration with some countries from the Middle East and North Africa. Since late 2010 he is also the CERN Scientific Coordinator of the AIDA program.

Tadeusz Kurtyka
Russia, Eastern Europe, Central Asia

Jose Salicio Diez
Latin America

Jose Salicio received a PhD degree in Experiment Particle Physics from Universidad Autonoma de Madrid (Spain) in 1981. He started his research work as particle physicist in 1976 at CIEMAT (Spain) where he took part in the data taking, measurement, and analysis of experiments performed with the 2 meter hydrogen bubble chamber at CERN. In the middle of 1981 he was commissioned to the German laboratory DESY (Deutsches Elektronen-Synchrotron), Hamburg, in the MARK-J Collaboration leading the physics analysis group from the Particle Physics Division of CIEMAT. He has participated in the analysis of e+e- interactions, such as muon pair production and inclusive muon production. In the period 1983 to 1989 he contributed to the design and construction of the L3 experiment. In 1986 he took the function of Technical Co-ordinator to organize the production of components and assembly of the L3 muon spectrometer. In 1990 he became CERN staff leading the EP-L3E group. In September 1994 he moves to the Personnel Division as Head of the Recruitment Service (RES) where he was Secretary of the Selection Committees for Fellows, Scientific Associates and Students (FAS). In June 2001 he becomes Divisional Planning Officer (DPO) of the Experimental Physics (EP) Division and Head of the EP-ABS Group (Administration and Budget) that later in 2009 was renamed (PH-AGS) and enlarged with the inclusion of the User Office (UO) and Space Management (SMI) groups. From 2004 he also coordinates the relations of CERN with Latin American countries.

Emmanuel Tsesmelis
South-East Asia, Oceania, Cyprus, Iceland, Ireland, Israel, Malta, Turkey

Professor Emmanuel Tsesmelis is an experimental particle physicist and member of the CERN Directorate Office and Visiting Professor in Particle and Accelerator Physics at the University of Oxford. He undertook his studies in Athens, Melbourne and Dortmund. He completed his Ph.D. studies in experimental particle physics at the University of Dortmund, where he worked on the search for the charged Higgs on the UA2 experiment at CERN. From 1993 to 1998, he worked on the NOMAD and SPY neutrino experiments and on the design stages of the CNGS neutrino beam. In 1998 he joined the CMS Collaboration at the LHC and for the period 2005-2008 he was Head of the LHC Experimental Areas. He has also led the CLIC machine-detector interface working group. Emmanuel has also served as Physics Co-ordinator for the SPS and PS programmes at CERN. As of 2004, he has been providing strategic advice to CERN Directors-General on international relations, and in this capacity he has been responsible for bringing into collaboration with CERN scientists from countries that are in the process of developing their particle physics communities. He also lectures in physics and participates in science communication events, most recently related to CERN’s Non-Member State Summer Student Programme and High School Teacher Programme and at the Royal Society’s Summer Science Exhibition in London.

Rudiger Voss

Rüdiger Voss obtained a PhD in Experimental Particle Physics from the University of Munich (Germany) in 1982, where he continued to work as a post-doc, and has been a CERN Staff member since 1987. Following early work at the CERN Intersecting Storage Rings (ISR), his scientific activity has been primarily in deep inelastic muon scattering at the CERN SPS, and in the design and construction of the ATLAS experiment at the LHC of which he has been a founding member. In parallel, he has held several managerial positions at CERN, such as SPS Physics Co-ordinator and Deputy Division Leader of the Experimental Physics Division. He has been a member of several CERN, national, and international scientific committees, and is presently Chairperson of the CERN Associates and Fellows Committees. In addition, he has always pursued a strong interest in scientific publication matters, especially in the Open Access movement. Since 2009, he represents all CERN experiments in the office for International Relations.

Jean-Pierre Koutchouk

Jean-Pierre Koutchouk holds a diploma of Ingenieur en genie Physique, INSA, Lyon and received his PhD in 1973 while working at the French Centre National d’Etude Spatiale. After a period as research associate in the Computer Science department of Sir George Williams University, Montreal, he joined CERN in 1975. He is now accelerator physicist, oriented towards beam optics, machine performance and machine design. He worked in several CERN groups: ISR Operations, LEP Theory, LHC Accelerator Physics, Beam Instrumentation and Superconducting Magnets, and presently in the DG/Project Office. He contributed to and led the LEP Optics commissioning (1989), the LEP Polarization program (1990-1993), the design of the LHC optics and layout(1994-2000) and then chaired working groups on the specification of the LHC beam instrumentation and specification and follow-up of the LHC magnet field quality. He is project coordinator of the FP7 EuCARD Accelerator R&D Project since 2008 and involved in studies on the LHC luminosity upgrade. He represents the accelerator and technology sector in the CERN international Relations Office since 2009.
