Biography

Xavier Amatriain is Researcher in Telefonica R&D Barcelona where he joined in June 2007. His current focus of research is on Recommender Systems, Social Networks, and other Web Science related topics. He also continues some work on other research lines such as Multimedia Systems.

Previous to this, he worked at the University of California Santa Barbara  as Research Director of the CREATE center. There he was also Technical Director of the Allosphere project and taught courses in the MAT program.

Xavier Amatriain studied Telecom Engineering (ECE) at UPC and did his PhD on Computer Science at UPF , both in Barcelona. During and after his Phd he was researcher and project manager in the Music Technology Group and Associate Professor at UPF's Technology Department where he taught Software Engineering and other topics such as Audio Processing, Data Structures...

In his spare time he also coordinates the CLAM project.
