Before joining CERN in 1978, he was employed for five years by SESA in Paris. At CERN, he has been in charge of external networking for more than 12 years and held positions in infrastructure and application networking, including the management of CERN's World-Wide Web team after the departure of the Web inventor Tim Berners-Lee. He is an adviser to the European Commission, a member of the Internet Society Advisory Council and the author of the reference textbook "Understanding Networked Multimedia" as well as more than 80 articles. He has 37 years of experience in networking and information technologies. François Flückiger graduated from the Ecole Supérieure d'Electricité in 1973 and holds an MBA from the Enterprise Administration Institute in Paris in 1977.

Bob Jacobsen

Bob Jacobsen is an experimental high-energy physicist and a faculty member at the University of California, Berkeley.  He's a member of the BaBar collaboration, where he lead the effort to create the reconstruction software and the offline system.  He has previously been a member of the ALEPH (LEP) and MarkII (SLC) collaborations. His original academic training was in computer engineering, and he worked in the computing industry before becoming a physicist.


Sverre Jarp


Sverre Jarp is active in the CERN openlab, a joint collaboration with leading industrial partners in order to assess cutting-edge information technology for the Large Hadron Collider’s Computing Grid.  He has been working in computing at CERN for over 35 years and has held various managerial and technical positions promoting advanced but cost-effective computing solutions for the Laboratory.  In 2001-02 he spent a sabbatical year in HP Labs (Palo Alto, USA). His current fields of interest are, in particular, multi-threaded programming and performance tuning, but he works hard to keep involved in all the technical activities in openlab. S. Jarp holds a degree in Theoretical Physics from the Norwegian University of Science and Technology (NTNU) in Trondheim.

Sebastian Lopienski


Sebastian Lopienski is CERN’s deputy Computer Security Officer. He works on security strategy and policies; offers internal consultancy and audit services; develops and maintains security tools for vulnerability assessment and intrusion detection; provides training and awareness raising; and does incident investigation and response. During his work at CERN since 2001, Sebastian has had various assignments, including designing and developing software to manage and support services hosted in the CERN Computer Centre; providing Central CVS Service for software projects at CERN; and development of applications for accelerator controls in Java. He graduated from the University of Warsaw (MSc in Computer Science) in 2002, and earned an MBA degree at the Enterprise Administration Institute in Aix-en-Provence in 2010. His professional interests include software and network security, distributed systems, and human aspects of information security.

Pere Mato Vila


Pere Mato studied physics at University of Barcelona, Spain, where he obtained the Ph.D. in 1990. Since 1986 has been working at CERN in a number of projects. Started with the 3081/E emulator project at the DD division, and later moved to the Aleph experiment in the area of DAQ and slow controls. In 1994 he took the overall responsibility of the Aleph TPC detector until the end of LEP. Since 1998 he has been leading the development of the core software and framework for the LHCb experiment (Gaudi) and later the LCG Core Libraries and Services project (SEAL). In 2005 has been appointed Applications Area manager of the LCG project.


Axel Naumann


Starting off as a physicist, Axel studied physics and math at Muenster, Germany. In 2000, he got a PhD position for high energy physics at Nijmegen, The Netherlands. They sent him to Fermilab at Chicago, where he worked with the D0 experiment - which also meant writing software from PCI drivers to data analysis code. During that time he got involved with ROOT, slowly converting from a user to a developer. He contributed to whatever he needed, e.g. the statistics part, the documentation engine, and porting it to cygwin. After a position with the Fermilab Computing Division in 2005 he ended up at CERN in the ROOT development team. He is now responsible for the reflection system, the interpreter CINT, and the documentation system.


Andrzej Nowak


Andrzej Nowak is a staff researcher at CERN openlab - a collaboration of CERN and industrial partners such as HP, Intel, Oracle and Siemens. He holds a Master Engineer degree in Computer Science from the Gdansk University of Technology, specializing in distributed applications and internet systems. Andrzej's early research concerned operating systems security, mobile systems security, and wireless technologies. During his studies in 2005 and 2006, he worked at Intel, where he researched custom performance optimizations of the Linux kernel and took part in developing one of the first implementations of the IEEE 802.16 "WiMax Mobile" standard. In January 2007, soon after obtaining his diploma, he joined openlab as a Marie Curie Fellow sponsored by the European Commission. Andrzej's current research is focused on performance tuning, parallelism and modern many-core processor architectures. Another significant area of his work is the teaching of these topics at courses both within and outside of CERN.

Alberto Pace


Alberto Pace is a member if the IT department at CERN where he leads the Data Management group ensuring a coherent development process for Physics Data management activities, strongly driven by operational and user needs.
