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.

Bergische Universität Wuppertal - Germany

I studied computer science at the University of Applied Sciences, Münster, and got my master's degree in 2007. In 2008, I started to work on my PhD thesis at the ATLAS working group of the University of Wuppertal. I am continuing development on the user space job monitoring software, JEM, created at Wuppertal, and focus on the user interface (integration in the job submission and management tool 'ganga') and a binary tracing module allowing to monitor.(athena-) user algorithms written in C++.

Andrea PARENTI

DESY, Hamburg - Germany

I am working at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg, Germany, for the ZEUS and CMS experiments. I am the Monte Carlo Coordinator for the ZEUS experiment: my tasks are to guarantee a smooth processing of Monte Carlo events, coordinate people working on the simulation software, build-up new versions of the Monte Carlo software.   I also made analysis of the ZEUS data using Fortran and PAW. In CMS I am involved in the alignment of the silicon tracker. I am responsible for a package of perl scripts helping in managing a large amount of alignment jobs. I am also doing alignment studies with Monte Carlo events; the software we use for this is C++/root based.

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.
