I work on the CernVM R&D project in PH-SFT. CernVM provides a portable environment for development and execution of LHC experiment analysis software. In particular, I develop the CernVM File System, an HTTP file system that brings software trees on demand onto virtual machines. As part of CernVM, I also deal with various aspects of virtualization, including benchmarks of HEP software in virtualized environments. As part of my thesis, I work on distributed algorithms in order to build a self-organizing network of virtual machines out of a plain cluster installation. Currently I mainly develop system software on Linux using C/C++ and a couple of scripting languages. I have working knowledge of LateX and Gnuplot.

I have been working for the TT sub-detector of LHCb during both my Bachelor and my Master thesis. Since January I am back with my previous group as a PhD student. At the time of this writing my work concentrates mostly on the detector alignment.

University of Cambridge – U.K.

CI am currently working on physics analysis in the Atlas experimental collaboration. My studies include data driven background estimation techniques for use in searches for new physics such as supersymmetry, and separately a measurement of the top quark mass in the dileptonic decay channel of top pair events. I am familiar with working in the Linux environment both the Scientific Linux CERN distributions as well as Redhat Fedora distributions. I am comfortably familiar with the C++ programming language, and I am also quite familiar with the python scripting language. I use the bash shell environment for scripting as well.

I am currently working on the development and the deployment of the core software for the population of DB accounts in different RDBMS technologies with condition data coming from the CMS detector, using Object Relational Access. I am also developing tools, which, using the dropbox technology, allow the automatic population of the Condition Database. All the logs of the transactions are persistently stored, and monitored by applications that have a web GUI, thus allowing for real time monitoring, and fast detection of errors.

CERN, Geneva - Switzerland

I am currently working on the commissioning of the ATLAS software for the reconstruction of particle tracks and the identification of b-quarks in particle jets (b-tagging). As part of this work I am studying the resolution of the track impact parameter in transverse direction, which is one of the most important inputs for b-tagging. I am developer of several C++ reconstruction algorithms and tools, and the main responsible for the production of the b-tagging performance analysis data format (a ROOT ntuple). I am familiar with Linux, Mac OS X and Windows operating systems. The largest part of my work concerns programming in C++, but I also have good knowledge of Python, Delphi, SQL and HTML.

Pablo GUERRERO

CERN, Geneva - Switzerland

Last year I finished my Master's Thesis on Computer Science at the Zaragoza University (Spain) doing an internship as Technical Student at CERN. I worked developing an automatic solution for the RPM generation process for different Oracle products, written in object oriented Perl.  After that, I worked for 3 months for Warp, a consulting company working with Open Source platforms, implementing new features for web applications written in Python and Ruby. In August 2009, I came back to work at CERN as Fellow in IT-GT, working for gLite, a Grid middleware used for the LHC Computing Grid.  I am a member of the gLite integration team, performing the tasks needed to release new versions of the middleware. I also have to participate in the modification of the integration process and implement the changes in the software used in the process.
