Studied Physics at Universitat de Barcelona (UB) in 1997, where also obtained his PhD (European Doctorate and PhD Extraordinary Award) in 2001. He worked as Assistant Professor at UB (2001-2009). From 2009 to 2015 he was ICREA Prof. at Institut de Ciència de Materials de Barcelona, ICMAB-CSIC. Since 2015 he is ICREA Prof. at Institut Català de Nanociència i Nanotecnologia (ICN2) and Leader of the Advanced Electron Nanoscopy Group. President of the Spanish Microscopy Society (SME) (2017-2021), Vice-President (2013-2017) and Executive Board Member (2009-2021). Executive Board Member of the International Federation of Societies for Microscopy (IFSM) (2019-2026). Founding member of e-DREAM. Scientific Coordinator of the Joint Electron Microscopy Center at ALBA Synchrotron (JEMCA). Since 2023 Associate Editor of Nano Letters (ACS). Received the FWO Commemorative Medal (Flanders Research Foundation) in 2021, the BIST IGNITE Award in 2018 and awarded with the EU40 Materials Prize 2014 (E-MRS)

Explore by means of electron microscopy and related spectroscopies the structure-properties relationships in nanomaterials for physical applications (photonics/plasmonics/phononics/electronics/quantum) adding AI-based methodologies for advanced automated data analysis (deep and machine learning). Understand the behavior of nanomaterials for energy and environmental applications down to the atomic scale and create in-situ and correlative methodologies combining electron microscopy, synchrotron and AI.
