He is a Telecommunication engineer and Ph.D. from the Universitat Politècnica de Catalunya (UPC). His Ph.D. Thesis was focused on designing and implementing a multivariate approach-based system for automating the data interpretation process using matching-based and machine learning (ML) techniques applied to the artistic pigments recognition through Raman spectroscopy in art analysis, crucial for the conservation, restoration and authentication of art works.

He joined the European Space Agency (ESA) Gaia Mission in January 2012 as a Gaia DPAC engineer. Currently, he is the Software Project Manager of one of the cornerstone systems of the ESA Gaia Mission. In particular, the system (namely IDT) is devoted to the Gaia satellite telemetry processing in a daily real-time manner, and is a key system for achieving the challenging Gaia Mission goals on astrometry, photometry and spectrometry of more than one billion objects of our galaxy -the Milky Way- and beyond.

Previously, he was working as a software and testing engineer mainly focused on implementing and validating scientific and technical developments in IDT, in the data handling, management and arrangement system (namely DPCB), and in the Gaia cyclic processing through the global astrometric data updating system (namely IDU) within the Barcelona Supercomputer Center (BSC) using mainly the MareNostrum supercomputer.

Also, he was working in a challenging project, the Gaia Cross-Match (XM), where he was in charge of designing, developing, analysing and implementing a XM algorithm making use of ML techniques in order to determine and use the sky coordinates derived from the Gaia astrometric observations using the latest satellite attitude and calibrations, providing a single optimal link for each Gaia observation.

In addition, he was working as the Test Manager of IDT, DPCB and IDU. Among his main responsibilities he supervised and supported system test campaigns, and also performed data and software validation and verification tests, reporting through European Cooperation for Space Standardization (ECSS) guidelines.
