M.S. and Ph.D. degrees in Telecommunication Engineering, both from the Technical University of Madrid (UPM), Spain, in 2003 and 2007, respectively. He was granted by UPM to proceed with his Ph.D., being finally recognized with maximum qualification (Sobresaliente Cum Laude) and Doctor Europeus mention. From 2003 to 2005 he was involved in the ADVOCATE2 project (IST-2001-34508), funded by the V Framework Program of the European Union. He worked as visiting research fellow in two European research centres: Cemagref, an agricultural and environmental engineering research centre located at Montpellier (Languedoc-Roussillon, France), and European Centre for Soft Computing (ECSC), located at Mieres (Asturias, Spain). Later, he was postdoctoral researcher in the “Fundamentals of Soft Computing” Unit at ECSC from November 2007 to January 2012. In June 2010, he worked as visiting research fellow in the Università degli Studi di Bari (Dipartimento di Informatica). Then, he was “Juan de la Cierva” postdoctoral researcher funded by the Spanish Government under project JCI-2011-09839 in the Department of Electronics at the University of Alcala (UAH) from February 2012 to October 2012. From November 2012 to May 2016, he was Deputy Principal Researcher in the “Computing with Perceptions” Research Unit at ECSC. From June 2016 to January 2018, he was postdoctoral researcher at CiTIUS. From February 2018 to December 2022, he was "Ramón y Cajal" researcher funded by the Spanish Government under project RYC-2016-19802 in the Intelligent Systems Research Group of the University of Santiago de Compostela. From January 2019 to December 2022, he was board member of the ACL Special Interest Group on Natural Language Generation (SIGGEN). From September 2013 to September 2019, he was board member of the European Society for Fuzzy Logic and Technology (EUSFLAT). He was Chair of the Doctoral Consortium at the European Conference on Artificial Intelligence (ECAI2020). He is currently Associate Professor at the Department of Electronics and Computation of the CiTIUS-USC, Chair of the Task Force on “Explainable Fuzzy Systems” in the Fuzzy Systems Technical Committee of the IEEE Computational Intelligence Society (IEEE-CIS), Associate Editor of the IEEE Computational Intelligence Magazine (ISSN: 1556-603X)(Q1 in ISI-JCR) and the International Journal of Approximate Reasoning (ISSN:0888-613X) (Q2 in ISI-JCR), member of the IEEE-CIS Task Force on Fuzzy Systems Software, member of the IEEE-CIS High School Outreach Subcommittee. He has been Honorary Research Fellow in the University of Aberdeen (Scotland) in 2016 and Research Fellow in the University of Bari "Aldo Moro" (Italy) in 2017. He has published more than 170 papers in international journals, book chapters and conferences. His research interests include explainable and trustworthy artificial intelligence, computational intelligence, interpretable fuzzy systems, natural language generation, development of free software tools, etc.
