I got my PhD in Computer Science on 16/10/2009 with the thesis titled “Integration and Disambiguation Techniques for Semantic Heterogeneity Reduction on the Web”, supervised by Dr. Eduardo Mena.

Member of the  Distributed Information Systems Group (University of Zaragoza), led by Dr. Eduardo Mena and previous member (2009-2017) of the Ontology Engineering Group (Universidad Politécnica de Madrid, Spain), led by Prof. Asunción Gómez-Pérez . I also worked at Knowldege Media Institute (Open University, United Kingdom ) as Visiting Researcher from March to July 2007, and on June 2008 (see more… ), in Enrico Motta’s group. I was also Visiting Researcher at Institut National de Recherche en Informatique et en Automatique (INRIA), Grenoble (France) in June 2012 and from May to July 2013, working in Jérome Euzenat’s group. From October to December 2014 I collaborated at Università di Roma “La Sapienza” with Roberto Navigli and his group in topics related to BabelNet and Linked Data. In July 2016 I visited the Semantic Computing Group at CITEC (Center of Excellence – Cognitive Interaction Technology) at University of Bielefeld for one month, to collaborate with Philipp Cimiano in the topic of linguistic linked data.
