I am a research fellow in the field of Knowledge evolution in distributed collaborative systems at the Department of Information Engineering and Computer Science of the University of Trento - Italy, where I received my Phd in Informatics in the topic of Distributed Identity Management. I received my Informatics Engineering degree at the National University of Asunción in Paraguay.

My major research interests include knowledge evolution and propagation in heterogeneous distributed collaborative systems, including areas such as entity identification, entity compatibility and matching, semantic matching and trust and reputation models.

I was in charge of the directory track on the Ontology Alignment Evaluation Initiative in 2008, 2009 and 2010 and I am one of the contributing authors of S-Match an open-source semantic matching system.

I actively contributed to the EU funded OpenKnowledge project in the area of semantic matching and to the Insemtives project in the areas of semantic annotations models and semantic disambiguation in Folksonomies and their evolution in time.
