From L to M
LAZARIDIS Christos CERN, Geneva - Switzerland
  Although a computer geek since ever, I studied physics in the Aristotle University of Thessaloniki. Afterwards, I did my PhD studies at the University of Wisconsin-Madison. During that time I was based at CERN working on the hardware commissioning and the operational software of the CMS Level-1 trigger while preparing my physics analysis in ROOT and C++. Currently, I am a CERN fellow working on the LAGUNA-LBNO design study. Throughout these years I also gained valuable experience in Python, Linux system administration and shell scripting. I am a tinkerer by nature, enjoying breaking things apart and putting everything back in place (successfully most of the times!).
LETTENBICHLER Jakob HEPHY, Vienna - Austria
  I am working on a track finding module specialized for low momentum tracks in the Silicon Vertex Detector (a double-sided strip detector) of the Belle II experiment (Tsukuba, Japan). Transverse momenta (pT) down to 50 MeV/c (high deviations due to material effects) shall be reconstructed and only a small number of layers are available (3-4 layers depending on pT), while facing considerable background, mainly Bhabha-Scattering and Touschek effect. We plan to deal with it by combining 3 different techniques: a Cellular Automaton produces track candidates (TCs) which are filtered by a Kalman filter which calculates quality indicators for each TC. These quality indicators are used by a neuronal network of Hopfield type to determine a reasonable set of TCs which do not share hits. I am currently working using linux (ubuntu) and am familiar with Microsoft Windows too. C++ and Python are the languages I use most. Basic knowledge for C and Octave (Matlab) does exist too.
LJUNGGREN Martin Lund University - Sweden
  I finished my master's degree analysing test beam from a prototype time projection chamber (TPC) constructed by the LCTPC collaboration for R&D towards a detector for the ILC. I have since started a PhD in the Alice collaboration and am currently involved in studies for an upgrade of the Alice TPC, where I am analysing test beam data from a prototype (GEM-based) readout system. I am also working on simulations of the upgraded TPC. Here I use mainly ROOT and possibly Geant in the near future. Another part of my Phd-work is the analysis of anisotropic flow of protons, pions and kaons in Pb-Pb collisions using data from the Alice-experiment. Here I use mainly ROOT (and AliROOT). Other than C++, I am somewhat familiar with Fortran and Matlab. In operating systems, I am familiar with Linux and Windows.
LOBATO Lorena CERN, Geneva - Switzerland
  I studied a BTEC in Telecommunication Systems, and after that, I obtained a Master's Degree in Computer Science at the University of Vigo. Afterwards, I worked for different companies as a System Analyst, Programmer, Database Manager and IT Consultant. In 2011, I joined CERN as a Technical Student in the PH-ESE group, to work on software development for a GLIB project. When I finished, I joined the IT-DB group as an Openlab Fellow, sponsored by Oracle, to work on Oracle replication technologies.
LÓPEZ GONZÁLEZ Juan CERN, Geneva - Switzerland
  I work for GS-AIS-GDI in development and maintenance of the applications of the group (Phonebook, public outreach, e-groups, roles, foundation data...) I am also responsible of the maintenance and administration of the deployment/build/monitoring infrastructure in GDI section. Programming languages: C++, C#, Java, Groovy (Grails) and Lisp. Others: Maven, Bamboo, Nexus, Atlassian tools.
MALTA RODRIGUES Alan Universidade do Estado do Rio de Janeiro -  Brazil
  I am a digital system engineer currently working at CERN in the CMS experiment, being part of the Cat-A program for Rio de Janeiro State University. My main responsibility for the last 2 years was in the time critical production of Release Validation (RelVal) samples that are used for the CMSSW software validation, with the use of the Grid Computing infrastructure. In addition to that, I have been working together the Workflow Team monitoring and solving issues arisen during the MC production and Data reprocessing. Finally, I just started the migration process from the RelVal to the CMSWEB operations, where the latter provides central and critical services to the CMS community.
MANCINELLI Valentina CERN, Geneva - Switzerland
  I studied computer science at the University of Perugia, in 2011 I obtained the master degree with a thesis on the development of a monitoring system for grid services based on NoSQL database. The same year I started working at CERN. At the moment I am participating on the Common Analysis Framework project which aims is to build a common system for the Distributed Analysis for ATLAS and CMS experiments. The CAF core system is based on PanDA(Production ANd Distributed Analysis system, a Pilot-based workflow manager of ATLAS) . I worked first in the development of the prototype of the TaskManager layer for CMS that manage user requests breaking them in PanDA units (job). Currently I am responsible for the modularization of the PanDA pilot code taking care to implement the CMS specific modules.
MANZALI Matteo INFN, Bologna - Italy
  I am an Italian PhD student at the University of Ferrara and I had the master degree on Computing Science at the University of Ferrara (2011). My master dissertation focused on the development of a DAQ software for the prototype of a muon detector and the central goal of my PhD is the study of new parallel programming solutions and tools in many-core era. I am also working for the INFN-CNAF institute as researcher in the R&D group. Here I am working on the parallelization of existing algorithms in physics applications for online and offline analysis (using Intel tools) and the use of new coprocessors. Before that, I have worked on the design and implementation of a private IaaS infrastructure to provide VMs on demand (using OpenStack).
MANZI Andrea CERN, Geneva - Switzerland
  I am a computer scientist graduated from the University of Pisa in Italy. After working 3 years as a research fellow at CNR (the Italian National Research Council) and 1 year in a private company (IONTrading) as software developer, I have started working at CERN in 2009 and I am currently holding a staff position in the IT Department. I am involved in the EU project iMarine, having the roles of deputy technical director, WP leader and developer of solutions for data transfer. In parallel I am involved in the DPM project (grid storage), where I am the developer of an extension of the storage solution to Apache HDFS. My main programming languages are Java, C++ and C.
McCREA Alison University of California, San Diego -  U.S.A
  Currently I work for CERN Computing Operations, maintaining and improving the CERN-based portion of a pilot-based workload management system called glideinWMS (based on HTCondor), which processes Monte Carlo and user analysis jobs for CMS on the Grid. With the help of many others, I am currently expanding this infrastructure to allow usage of cloud clusters (such as the CMS HLT farm during LS1), as well as multicore and opportunistic resources, with the aim of preparing for the increased computational demand expected during the LHC's 2015 run. I have a B.S. in Physics from the University of California, San Diego, with a minor in Computer Science, which I received in 2011. My language of choice is Python, and I am also versed in xml, bash scripting, Java, C, C++, and various assembly languages.
MESSI Francesco Rheinische Friedrich-Wilhelms-Universität, Bonn - Germany
  I graduated in Physics working on the time-adjustment of the Front-End electronics for the muon chambers of the LHCb experiment in the electronics group of the university of Rome "La Sapienza". I worked one year in the didactic group of the university of Rome "Tor Vergata" developing didactical instrumentation for the high school. I started my PhD in 2009 at the "Rheinische Friedrich-Wilhelms-Universität" in Bonn on the Tagger Detector of the BGO-OD experiment at the ELSA accelerator. The main focus of my work is the development of the Front-End electronics (Amplifier, Dual Threshold Discriminator and Shaper). This includes the design of the PCB, the development of the firmware for the microcontroller and of the User Interface of the board, the commissioning of the boards and the analysis for the in-beam characterization of the prototype detector. I also contributed to the construction of the detector and to the implementation of the analysis tools. At present I am writing my thesis.
MONTUENGA Pedro University of Illinois at Urbana-Champaign – U.S.A.
  I did my undergraduate studies in Physics at Simon Bolivar University in Caracas, including a year at Lund University. I am currently pursuing a PhD at the University of Illinois. For about 1 1/2 years I have been involved in the COMPASS experiment at CERN, working on the design of new Drift Chambers 5 and 6. For the last six months I have also been involved in the PHENIX experiment at Brookhaven National Lab, NY; working on the calibration for the Muon Piston Calorimeter for the ongoing run13 and plan to do my dissertation work on the measurement of \Delta g, i.e., the contribution of gluons to the total spin of the proton. I work both in Linux and Windows. I program almost entirely on C++ (plus ROOT) for data analysis. I have used Java in the past and have some command of MATLAB and Labview.
MORENO PASCUAL Fernando CERN, Geneva - Switzerland
  One of my main objectives here at CERN is to carry out the design, implementation and the deployment of a new Voice over IP telephony and Unified Communications service providing an enhanced telephony user experience for the whole organization. Moreover, I work on the administration of the Mail Service at CERN and I am an active member of the third level support on this service. The operating system mainly used on our section is Windows (XP/7/8/Server 2003/Server 2008), but I also feel comfortable working with Linux although I have less skills in this last one. About the programming languages that I am familiar with, I can say that C#, C++, C, Java, SQL, Powershell.
MORGENSTERN Marcus Technische Universitaet Dresden - Germany
  Currently I am PhD student studying heavy neutral particle decays at the ATLAS experiment. This involves analysing huge amounts of data. Hence, parallel computing is essential in the daily workflow. Furthermore, I develop tools used by several analysts and have been contributing to the ATLAS trigger and reconstruction software in the past. In general I use Scientific Linux/Mac OSX as main operating systems, but knowledge on Windows systems exists. I am very familiar with advanced C/C++ (98/11 – including external libraries like boost, tbb) and python. Basic knowledge in C#, Java, Scala, shell, SQL, Ruby, and R exists.
MORVAJ Ljiljana Nagoya University - Japan
  I studied at the University of Zagreb, Croatia, where I obtained a masters’ degree in theoretical physics. In 2009 I attended CERN summer school, where I got interested in high-energy experimental physics. In 2010 I enrolled in a PhD program at Nagoya University, Japan. Currently I am working on the data analysis in ATLAS, searching for physics beyond the standard model. My PhD thesis is titled "Searches for the Universal Extra Dimensions with the ATLAS Detector". The signature is characterized by low momentum leptons produced in the decays of the new extra-dimensional particles. For my analysis I am using Linux operating system, C++, Root and sometimes Python. I am also familiar with using the Grid for processing the data.
MUSHEGHYAN Haykuhi Universität Göttingen - Germany
  Originally I am Armenian and I have got my Master's degree in "Computer Systems and Informatics" department of State Engineering University of Armenia in 2008. Since 01.10.2012 I am a PhD student on "Grid computing" in II. Physikalisches Institut (Universität Göttingen). Currently I am working on two projects: ATLAS qualification task and HappyFace project. My qualification task is to extract some metrics from the logged data and make them available to the development team of AMI (ATLAS Metadata Interface). AMI is an official ATLAS tool for dataset selection since July 2006. This project uses JAVA as a programming language. The HappyFace project is a meta-monitoring tool to monitor the grid sites on different levels. This project uses Python as a programming language. Both projects use Scientific Linux as an operation system.
