​Born in Coimbra in 1978, Nuno Castro has lived in Braga since 2010.

He graduated in Physics from the University of Coimbra in 2000. He obtained a Master's degree in Physics from the Instituto Superior Técnico of the University of Lisbon in 2003 and a PhD in Physics from the University of Coimbra in 2008. He was a post-doctoral researcher at the University of Granada, Spain, between 2008 and 2010.

He joined the University of Minho in 2010 and is currently an Associate Professor in the Department of Physics at the School of Sciences. He is a researcher at the Laboratory of Instrumentation and Experimental Particle Physics (LIP), where he was a member of the Board of Directors between 2015 and 2025.

He has been collaborating with CERN – the European Laboratory for Particle Physics – for over twenty years, joining the ATLAS collaboration in 2004. He has been responsible for several physics subgroups within this collaboration, notably coordinating the Top Quark Properties (2012-2014) and Heavy Quarks, Top and Composite Higgs (2015-2016) groups. He was also a member of the Speaker's Committee of the ATLAS Collaboration (2020-2023) and co-coordinator of the CERN Large Hadron Collider (LHC) working group dedicated to the study of effective field theories (LHC EFT WG, 2020-2022). He represented Portugal in working groups of the CERN Council and in the Financial Review Committees of the ATLAS, CMS, Amber, SND@LHC and DUNE experiments.

His teaching activity encompasses more than a dozen courses in different study cycles, focusing on general physics, nuclear and particle physics, data analysis and processing, computational physics and science communication. He has supervised and co-supervised more than twenty doctoral and master's theses, addressing topics such as precision measurements in particle physics, search into new physics phenomena, machine learning, anomaly detection and quantum computing in high-energy physics. He coordinated the Master's Degree in Physics at the University of Minho (2019-2021) and was Vice-President for Research and Scientific Innovation at the School of Sciences (2021-2025). He was also a member of the General Council of the University of Minho in 2025.

He is the lead author of more than sixty articles published in international scientific journals and has participated in hundreds of collaborative publications in the context of the ATLAS and DELPHI experiments at CERN. As a member of the ATLAS collaboration, he received the Breakthrough Prize in Fundamental Physics (2025) and the EPS Prize for High Energy Physics (2013). He has coordinated and participated in several national and international scientific and innovation projects. He was Chairman of the Board of Directors of the National Centre for Advanced Computing (formerly the National Distributed Computing Infrastructure) between 2021 and 2025, and is currently a member of its Board of Directors.

He is a member of the Portuguese Physics Society, where he is co-coordinator of the Particle Physics division and chairs the Financial Board.
