In 2010 and 2011 I was leading the services and production group at PIC. In February 2012 I joined IT department at CERN. I'm currently working in the Data Storage and Services group.
Edgar FAJARDO Universidad de Los Andes, Bogota - Colombia

I am a Computer Scientist and Mathematician. I came to CERN to work as the Team Leader of a Workflow Team for CMS Computing Operations as part of the Cat-A program for Los Andes University. The main objective has been to operate central processing and production workflows using all CMS Computing Resources (Tier 1 and Tier 2/Tier3 levels) to achieve a 99% efficiency in the production and processing of CMS MonteCarlo and Data. It involves the coordination of a team of worldwide distributed operators (United States, Belgium and CERN) in order to achieve almost 24 hour coverage at monitoring of the production system. My main interest is computing and mathematics applied to other domains of science. Specifically I am interested on how to run more jobs in a faster way and in Computer Graphics to provide visualization aid.

Sergio FERNANDEZ CASADO CERN, Geneva - Switzerland
    Currently I am working at CERN, in IT-OIS group. I work on the CERN Search Project, an enterprise search solution where I have to support all the operational aspects needed. I’m also doing several developing tasks, like the creation/update of document extraction and processing pipelines of the engine, automation on common tasks, or developing new front-end webpages. Previously, I worked as a PHP web developer, as a teacher, and as a RFID applications developer (including RFID devices integration).  I have experience working with Windows and Linux, and I am comfortable developing in C#, Java (ME and SE), C++, PHP, and nowadays, also with Python.
Anders FLODERUS Lund University - Sweden
    I first started working at CERN during my MSc project, where I developed analysis software for LUCID, one of the luminosity monitors in the ATLAS experiment. At the start of my PhD, I continued this task while also taking up the role as the main developer of the Online Luminosity Calculator (OLC). This is a C++ program that calculates the luminosity in ATLAS, as well as various beam diagnostics, based on hundreds of measurements made by different subdetectors. The required information is collected by OLC in real time over various channels in the ATLAS online world, such as the Information Service (IS) and the Data Interchange Protocol (DIP). As of late, my focus has started to shift towards SUSY searches within the ATLAS 2-Lepton group. I have extensive experience with C++ and ROOT, and to a somewhat lesser degree with C, Java and Matlab.
Gorm GALSTER CERN, Geneva - Switzerland
    I am a physics student from Denmark, currently working at CERN as a technical student with virtualization and long term preservation strategies for ATLAS trigger code. I have always had a strong interest for computer science and have supplemented my physics classes with classes from the computer science department. In particular I have a personal and professional interest in IT security, multiprocessing and virtualization, for the latter two especially where/how they merge with high energy physics.
Jaime GARCIA LLOPIS CERN, Geneva - Switzerland
  Currently, I am working for the EU project "BlogForever". The main goal of this project (from CERN's point of view) is to extend Invenio in order to build an archival repository for blogs. It is not intended to be just a web archive for blogs: well-structured metadata, relations and citation between blogs and authors and semantic metadata will make it searchable, and will allow network analysis. The OS used for this project is GNU-Linux, and the main programming languages are Python and SQL. I am also a proficient user of Mac OS X and Microsoft Windows and I know C, C++, Java and some .Net and Perl.
Alberto GARCIA MOLERO CERN, Geneva - Switzerland
  I am a currently a Fellow in the Communications Systems Group of the IT Department. I am mainly involved in the deployment of digital radio communications systems based on the TETRA and UMTS standards. I am also working on solutions to improve the mobile telephone signal coverage in indoor and underground CERN facilities using femtocells, conventional distributed antenna systems and leaky feeder cables. The Master's program I completed was an interdisciplinary one, and included a strong emphasis on computer programming. I feel comfortable working with C,C++ and Java, under both Windows and Unix-based systems. In addition, during the last year of my studies I collaborated with engineering faculty in the modeling of wireless communications systems using Matlab.
Roman GREDIG University of Zürich - Switzerland
  I am member of the Mu3e experiment which is currently under development and designed to search for the lepton flavour violating decay of the muon to three electrons. The experiment will be operated at the Paul Scherrer Institut, Switzerland. Currently I am working on the simulation of the main detector using Geant4. I studied physics at the University of Zurich where I did my Bachelor and Master thesis for the Cherenkov Telescope Array experiment. I developed an automatic mirror control system that allows to align the telescope-mirrors. Since October 2011 I'm working as a PhD student.
Martin HELLMICH CERN, Geneva - Switzerland
  I am currently a fellow in the Grid Data Management section at CERN. I am involved in EUDAT, a project to design and build a common data infrastructure for researchers in Europe.  I studied Computer Science in Magdeburg, Germany and Distributed Scientific Computing in Edinburgh. The latter brought him in contact with the WLCG and CERN, so I decided for a openlab internship. My interests lie in large-scale data management and processing, as well as machine learning and all its applications. If I do not work, I am either biking or skiing, depending on the weather.
Teodor IVANOAICA National Institute for Physics and Nuclear Engineering Horia Hulubei – Romania
  I graduated the Faculty of Physics Bucharest, also master's degree in physical computing.  At this time I am working as grid site administrator and security officer for Romania's LHCb Collaboration grid site, a site that is completely dedicated to the LHCb VO, also I am trying to offer support for all the software and hardware requirements that the group has. I am also one of the administrators for a bigger grid site that supports almost all CERN's VO's and also local VO's for users that want to run jobs in grid. I am in charge with upgrading and backing up the main services and data bases of our sites. I am CCNA (Cisco Certified Networking Associated, also CCAI the instructor certification for CISCO Academies) and I intend to become a Certified Networking Professional as we are trying to improve our sites connectivity. As future plan I am beginning to study the DIRAC system and data management as the group, which I am part of, is growing and also the grid site will need to meet all theri demands.
