Individual marks can be provided to students upon request, by email, to the Examination Coordinator, Ivica Puljak (Ivica [dot] Puljak [AT] cern [dot] ch)

Examination: facts and figures



34 multiple choice questions were proposed.
After deliberation, the jury decided that all 34 questions should be validated. However, as there was a possible ambiguity on question 30, two possible responses have ben considered as valid for this particular question (those having chosen one of these two responses obtained the point attached to this question).

Pass / No-Pass threshold

To be declared as having successfully passed the examination, the student must have replied correctly to 50% or more than 50% of the questions. 

Number of correct answers for successful pass

Any student having replied correctly to 17 or more than 17 questions has been declared as having successfully passed the CSC examination

Number of successful students

55 students succeeded in the examination (updated 24th of August 2012).


  • CSC Diploma will be handed over to the students at the occasion of  the closing ceremony.

  • The students with the highest marks will be announced at the closing session Friday 26th of August.

  • ECTS Certificates will be given together with the CSC diploma.


Individual marks will be available on demand by email, after the closing session only, from Ivica Puljak (Ivica (dot) Puljak  AT cern (dot) ch).

2012 Podium: Pictures and Bio

1st Mark
Martin RITTER Max-Planck-Institut für Physik, München - Germany
  I am from Germany and studied physics at the LMU Munich.  Currently, I am a PhD student at the Max-Planck-Institute for Physics, working primary on the pixel detector for the upcoming Belle II experiment. My main focus has been to work on the Belle II experiment on detector simulation and optimization, involving the development of the software framework and simulation of the pixel detector.  I am also involved in the mechanical design and cooling of this detector. In addition I'm doing a physics analysis for Belle about the time dependent CP-Violation of B mesons in the channel B0 -> D*+ D*- Ks with the full data set of the Belle experiment. My main development is done on Linux in C++ and python but I have also experience with many other languages (e.g. Java, PHP) and and SQL database systems (e.g. Postgres and MySQL)


2nd Mark
Samuele CARLI CERN, Geneva - Switzerland
  I currently work on the author disambiguation facility for INSPIRE, the CERN's digital library.My work is focused on approximating the solution of a hard, constantly evolving problem using high level techniques, parallel and distributed computing as well as crowd-sourcing based algorithm supervision; this involves research on cutting edge multi-staged data clustering algorithms, exploration of possibilities for optimization and parallelization of such algorithms and research in techniques to allow fast re- computation upon small input data changes. I am familiar with high level languages as Python (main language used in INSPIRE), matlab-like and java as well as C, C++. I am usually working with UNIX like operating systems.  I am as well a M.Sc. student in computer science at Università degli Studi di Firenze specializing in numerical analysis and parallel computing; I have broad and strong interests across many fields, especially physics, mathematics and electronics.


3rd Mark
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.

2012 Special distinctions: Pictures and Bio

In addition to the podium, the jury of the CSC examination is pleased to award  a special distinction to the five students below who obtained a mark of 30 and ranked 4th.

4th Mark
Christian ELSASSER University of Zürich - Switzerland
  I received my master degree in physics in 2011 from the University of Zurich, working in the field of very rare B decays at the LHCb experiment. Before I was setting up a test facility to monitor silicon sensors using IR lasers.  Subsequently to the master degree I started my PhD thesis where I've continued the work on very rare B decays, mainly in the context of particle identification. Further I am also developing a tool to monitor the radiation damage in the silicon trackers of LHCb and have just started to study hadronic tau reconstruction in LHCb which will be used in many Electroweak as well as Flavour Physics analyses.
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.
Wolfgang KIESENHOFER Austrian Academy of Sciences, Vienna - Austria
  I studied physics at the Vienna University of Technology and did my diploma thesis at the Institute of High Energy Physics were I analyzed test beam data from semiconductor test structures measured at SPS. I am now a PhD student, starting my 3rd year and I'm currently working for the CMS experiment. My primary interest is the search for super symmetry, but I also participated in the muon and the missing energy object groups.  I am currently working on a background estimation technique for SUSY decay channels with a single lepton in the final state. Operating systems I use in my daily work are Linux and OSX, sometimes Windows.  Programming languages I am familiar with are C++, Python and Matlab. I have also extensively used ROOT and RooFit during the last 4 years.
Ramón MEDRANO LLAMAS CERN, Geneva - Switzerland
  I work at the IT-ES group, in which I am the main developer and coordinator of HammerCloud, the functional testing tool for grid sites of ATLAS, CMS and LHCb. This tool submits more than 115,000 grid jobs world-wide daily and has improved the ATLAS analysis reliability by 50%. Also, I'm involved in the HelixNebula project, to develop a cloud computing infrastructure for science. Finally, I'm becoming and ATLAS Computing Manager on Duty.  I finished past year my Research MSc, after obtaining a MSc in Computing in Spain and currently I am also working in my PhD. Before CERN, I have worked at Google. I use, administer and maintain a cluster of 17 machines for HammerCloud, work with shell scripting, Python, SQL, high replication and high performance clusters.
Omar PERA MIRA CERN, Geneva - Switzerland

I am a software engineer working in the Computing Facilities group at CERN. Currently working in the Lemon Team, where we develop and support the monitoring framework for the CERN Computer Center. I am involved also in the new Agile Infrastructure project, focused on the development of new monitoring components that fits into the new infrastructure. Before coming to CERN, I did an internship in the European Bioinformatics Institute in Cambridge and the University of Bremen, with protein visualization and semantic web as domain fields, respectively. In the last 2 years, I've been launching Android applications in my free time. Originally from Spain, looking forward to the CSC!
