ABREU  Ricardo


I am a software engineer, currently working on the Atlas High Level Trigger (HLT) experiment, in cooperation with the Data Acquisition (DAQ) community. I had already worked in the HLT/DAQ already for two years, between 2008 and 2010, within the scope of a national Portuguese scholarship. Before that, I obtained my MSc(Eng) from the University of Lisbon, with a research project on the areas of computer graphics, artificial intelligence, and artificial humans and environments. In the period of 2010-2012 I worked at Nagravision, a company in Lausanne, at the digital TV business. I now have a CERN fellowship which started at 2012 and I am currently involved in the evolution of the original two-stage HLT into a dynamic single-stage HLT. I also work on the design and implementation of new HLT code to harness the computing power of current and upcoming multi- and many-core CPUs.




I studied Computer Engineering at the Universifty of Cadiz (Spain), and now, after being Technical Student and Fellow at CERN, I am a staff member of the IT department.
As a Fellow, I worked on a storage software used in the Grid, where I took a main role in the design and development of the new core libraries, and its HTTP/WebDAV front-end.

When I changed contract, I moved to the "File Transfer Service", which orchestrates the copying of files between different storage elements in the Grid. During my participation in both projects, I have mainly worked with C, C++ and Python on Linux platforms.



University of Catania. Italy

I obtained my MSc in Computer Science Engineering in January 2007. After working in the Distributed Systems research group at DIEEI of Catania University, last year I started a PhD at Dept. of Physics and Astronomy in Catania. My research activity has been mainly focused on meta-heuristics and scheduling algorithms in Grid Computing. I am currently involved in a project, founded by the Italian Ministry of Research that aims to develop a detection system able to detect radioactive materials inside containers, to counteract the illegal transfer, by means of muon tomography. It uses the secondary particles of cosmic rays revealing the deflection of these particles when crossing high Z materials. I deal specifically with track reconstruction issues and with the visualization of 3D tomographic images. OS I use in my daily work are Linux and OSX, sometimes Windows. C/C++, Java programming, and I have also worked with R, ROOT and GEANT4.




Since the end of 2006, I've been a software engineer in the ALICE data acquisition team. I've been working mostly on web-based applications such as the ALICE Electronic Logbook (ALICE's bookkeeping facility) and the ALICE Configuration Tool (ALICE's top-level configuration facility). I've also been contributing to the Experiment Control System, serving as database administrator and acting as liaison with ALICE's inner tracking detectors. In view of ALICE's planned upgrade for Long Shutdown 2, I'm currently involved in two working groups contributing to the design of ALICE's new software framework.
