I completed my MSc at the University of Buenos Aires in 1998 working on the measurement of the production cross section of direct photons at the D0 experiment (Fermilab, USA). Afterwards, I worked in Sweden as a member of the Astroparticle Group of the Royal Institute of Technology studying cosmic rays. I did my PhD (2003, University of Buenos Aires) measuring the properties of quarks and gluons in high energy collisions at D0. In 2003 I became a postdoctoral Fellow at Harvard University where I worked mainly at the CDF experiment (Fermilab) on top-quark physics and detector operations. In 2008 I joined the IFAE (Institut de Física d'Altes Energies) LHC-ATLAS experiment group as an ICREA Researcher. I am currently leading the ATLAS Detector upgrade effort at IFAE. In 2012 I became an ICREA Research Professor. 

Research interests

My research has been focused on high-energy experimental particle physics: understanding which are the fundamental constitutes of nature and how they interact. At the Fermilab Tevatron accelerator I have performed studies of QCD and the properties of the heaviest quark, the top quark. At the LHC accelerator at CERN I conducted searches for new physics in the top sector. I am leading a coordinated project to develop semiconductor pixel detectors for the ATLAS experiment. 3D pixel silicon sensors designed and produced at Barcelona were included in the innermost detector layer of ATLAS. Currently, a new generation of 3D detectors are being developed for the high luminosity LHC era. My recent work also aims to develop radiation hard silicon sensors for timing measuremes in HEP experiments. I am also co-leading two projects investigating silicon sensors for medical applications.
