I am currently doing my PhD in the University of Göttingen and I am working for ATLAS on physics analysis.  A good understanding of the computing environment and tools is necessary for doing analysis.   Therefore, I have already basic experience with ATHENA (ATLAS analysis framework), ROOT and Grid.

Gábor GAJDATSY

University of Szeged - Hungary

As a PhD student I currently work on my thesis at the Department of Optics and Quantum Electronics, University of Szeged. The main field of my work is resolution enhancement of confocal microscopes using tomographic image reconstruction. Besides I am a researcher of the Institute of Engineering and Materials Science at the University where I develop numerical battery models for the automotive industry.  Although these fields are relatively far from each other, both of them indicate a huge amount of numerical problems, such as algorithm optimization, boundary value problems, data storage and analysis, controlling actuators and sensors, etc. To solve these problems I use MATLAB scripts, C/C++ dynamic libraries and LabVIEW codes.

Ana Maria GASPAR MARTINEZ

CERN, Geneva - Switzerland

I am a computer engineer who currently works at CERN in the SFT group in the Physics department for SPI (Software Process & Infrastructure) project. This project, provides software support to the LHC experiments and LCG Application Area (LCGAA) projects. The main task is to provide a test system called Nightly Builds. This system allows the LCG projects to be built and tested every night. Each project is built in different configurations (set of versions of Application Area packages that are supposed to work together) and in different platforms (set of different operating systems, architectures and compilers). Also, the SPI project is in charge of the installation of external packages needed by the LHC experiments and the LCGAA projects. My work in this project is to develop a multithread version of the nightly builds system to allow the test system use the most part of the capabilities of the machines where it runs. The system is developed in Python and uses Qmtest as a testing tool. I'm also in charge of installing and upgrading the external packages and helping in the maintenance of the current nightly builds system version.

Carlos  GHABROUS

I have studied Telecommunication Engineering at the University of Málaga, Spain, with emphasis in Communication Systems and Telematics, and before joining CERN I was involved in the WiMAX technology certification program and test system's design.  I came first time to CERN in 2007 in order to finish my studies and write my master thesis, designing solutions for configuring remotely mobile devices and other mobile services. Currently, I hold a fellow position in IT/CS group and my work is related to the deployment and operation of mobile and radio services, and to the design and validation of new telecommunications network architectures. I mostly use PERL and PHP for self written applications, but I am also familiar with C and C++.

Stephan HAENSEL

HEPHY, Vienna - Austria

My work includes the simulation of detector layouts for future experiments like the upcoming upgrade of the CMS Tracker for the SLHC accelerator and the next generation International Linear Collider. This is done with LiC Detector Toy, a fast simulation tool for charged tracks based on MATLAB. I will be responsible for the programming parts of the online data acquisition for a test beam setup at DESY and the subsequent analysis of the obtained data. There a first prototype of a silicon external layer for the ILD experiment will be tested using the C++ based LCIO framework, which is the common data model for linear collider detector studies. In addition I will undertake the task of the analyses of various test beams with silicon microstrip sensors.

Christian HARTL

CERN, Geneva - Switzerland

In 2007 I joined the CMS experiment to work in the Level-1 trigger system, as a CERN doctoral student in physics. I am close to the trigger group of Vienna's HEPHY institute, which developed the Global Trigger, Global Muon Trigger, and Trigger Control System of CMS. My tasks currently focus on online software for the configuration, control, and monitoring of this hardware. I have developed web applications which serve GUIs for setup manipulation, hardware monitoring, and interaction with the configuration database. I have also designed the database storing full information about available Level-1 trigger menu versions of CMS.

I am a post doctoral research associate with the University of California Los Angeles. I am located full time at CERN working on the CMS experiment. My main work so far has been preparing an analysis for data based on Monte Carlo simulations. I am looking for high pT muons from new charge gauge bosons (W'). Most of my work involves running on the LHD Grid and on a local UCLA batch system and then analyzing the results. I am familiar with Linux/Unix and Windows and the programming languages C/C++, FORTRAN, Python, Perl, and Bash.

Pavel JEZ

Niels Bohr Institute, Copenhagen - Denmark

I am a Ph.D student at Niels Bohr Institute in Copenhagen.

At the moment I am involved in the commissioning and optimizing of the Tau trigger at the ATLAS experiment at CERN. My work is focused on the performance of the Tau trigger in the environment with multiple collisions per bunch crossing, so-called pile-up collisions. The study is done on the Monte Carlo samples produced with the Athena software framework.

For my analysis I am using ROOT and its toolkit for multi-variate analysis in particular. The goal of my study is to find an ideal set of observables which can be used to select events with hadronically decaying tau leptons with the top performance in terms of signal efficiency and background rejection.
