Benjamin RADBURN SMITH

STFC Rutherford Appleton Laboratory, Didcot – U.K.

I am a first year PhD student with the University of Manchester studying data mining and visualisation of particle physics datasets. I am currently based at the Rutherford Appleton Laboratory (RAL) in the UK working between the CMS group and e-Science Scientific Applications Group. The visualisation techniques I am investigating include parallel coordinates and the grand tour. The aim of the project is to create a program which is compatible with ROOT that will implement these techniques. The program is being written in C++ for Linux based systems but will be developed to run on other systems as well.

Alexander RUNDE

Georg-August University Göttingen - Germany

I have been a bachelor student at the University of Göttingen (Germany) for 3 year. Within the last year I have made contact with particle physics. In my recently finished bachelor thesis I have worked on a ROOT based analysis for the reconstruction of a light higgs boson in di-tau channel, produced in vector boson fusion. At the moment I am looking forward to my work at CERN within the stationed Göttingen’s group, where I will look into likelihood-distributions for top-quarks. Due to my work done in the bachelor thesis I am familiar with ROOT and #C."

Michal SIMON

CERN, Geneva - Switzerland

I am a doctoral student at Silesian University of Technology. I obtained MSc Eng in Computer Science last year, I worked at my MSc thesis at DESY in Hamburg. At the moment I am working as a CERN doctoral student in data acquisition group in CMS experiment. My thesis main goals are studies of scalability, analysis of performance (speed, memory consumption) and stability particularly in the areas of communication between Run Control System components, communication between the Run Control System and the applications, communication with the database. I am also working on development of a security component as well as design and implementation of fault tolerance in the system such as dynamic recovery of crashed processes, dynamic masking of faulty hardware or dynamic reconfiguration.

David SINUELA PASTOR 

CERN, Geneva - Switzerland 

My current work consists in the development of raytracing functionality inside the FLUKA simulator (http://www.fluka.org). Currently the only way to visualize the geometry given to the simulation is by 2d plane cuts drawn by gnuplot, the aim is to have a 3 dimensional representation of the geometry. The implementation is currently working, made in C language but thinking in a posterior conversion to FORTRAN 77. Given the limitations of FORTRAN 77, the main algorithm has been converted to be iterative instead of recursive, using a binary tree implemented in a fixed size array (there is not dynamic memory allocation in F77). Now I'm converting the code to FORTRAN and it will hopefully merged with the main FLUKA code by the end of this year. - I feel more comfortable working with linux systems. Languages: C, C++, Java, Ruby, Python, Fortran, Shell scripting, Javascript, etc. - I'll use my work at CERN as my thesis, and this year I'll obtain the MSc degree.

Therese SJURSEN

University of Bergen - Norway

I am currently a PhD student in the experimental particle physics group at the University of Bergen. So far my main focus has been on preparing analysis tools for the search for Supersymmetry in the ATLAS detector at the LHC. By analysing Monte Carlo simulated data the aim is develop methods to suppress background from well known Standard Model physics scenarios to enable discovery of new physics, such as Supersymmetry, occurring with a much lower probability in the experiment.  

Ugur Emrah SURAT

METU, Ankara - Turkey

After getting my bachelor degree in Astrophysics, I started to work as a MSc. student at METU in Turkey participating in the CMS Experiment at CERN. Last year I have initiated in Exotica Group where I dealt with Large Extra Dimension phenomenology particularly ADD model, looking for monojet channel. My contribution focused on applying the compatible L1 and HLT trigger and eliminating the detector effects for start-up conditions. I am also a member of Detector Performance Group in CMS where i involved in HCAL subsystem in parallel to my studies.

I am currently a technical student at the Online group of LHCb at CERN. My main tasks are development and improvements of the control system and error tracking for the data acquisition system. My work will be part of my M.Sc. thesis in physics from Chalmers University (Sweden). In my work I mostly use C, C++ and the SCADA system PVSS. I am also familiar with other computer languages as Java, PHP, Javascript, MySQL, Matlab, LaTeX, bash scripts. I use actively and configure different Linux/UNIX systems and occasionally Windows.

Bayram TALI

Cukurova Universiyt, Adana - Turkey

I am a PhD student at Cukurova University in Adana. We have a big group involved in the hadronic calorimeter (HCAL) of the CMS experiment. We contributed mainly to hadronic forward (HF) and CASTOR calorimeters which are   the forward detectors of CMS. Our group is also working on several physics topics like forward physics, heavy ions, SUSY search. I basically contributed to the construction, commissioning and test beam analysis of the CASTOR and also tested the PMTs to be used in CASTOR in our laboratory in Adana. In my analysis I used CMSSW, ROOT and C++. My work on CASTOR is still continuing. Before joining CMS I spent one year at Aristotle University of Thessaloniki as a member of the ARTEMIS project which was involved in Higgs analysis at ATLAS where I also used ATLAS software ATHENA.

Joni Jukka VÄLIMAA

Helskinki Institute of Physics - Finland

I am a graduate student and my studies are related to CMS GRID-computing and CMS physics analysis with GRID and PROOF. Currently I am developing our local GRID-system at University of Helsinki. Previously I was working for nine years with telephone switches and got familiar with real time computing and telecommunications. Most familiar I am with proprietary RTOs used in Nokia like chorusOS and DMX. As an user level I am familiar most unix variants and windows. Most familiar programming languages for me are C and assembly (mostly i386, somewhat powerPC), which I used in my previous work. More generally a can at least read C++, fortran and java, although I never have done any serious work with them.

Adrian VOGEL

Universität Bonn - Germany

I am currently working on software development for a fast simulation of the ATLAS tracking detectors, which means I'm programming in C++ within the Athena environment. My task is to implement a connection to the conditions data subsystem, allowing dead and noisy channels to be treated properly in the detector simulation. Before that, I worked at DESY and did simulations of beam-induced backgrounds in detectors at the International Linear Collider, trying to estimate the impact of background particles which get created in large amounts during each bunch crossing and which can then smash into the forward instrumentation. For these studies I did Geant4-based programming in C++ as well, but I also needed to deal with MySQL, PHP, XML, and some shell scripting. Furthermore, I gained some experience with the gLite middleware by running my jobs and storing my data on Grid resources.
