Paulo Villegas

Paulo Villegas works as a Technology Expert at Telefónica I+D. His main working fields are Digital Image & Video Processing (specially concerning content representation & analysis for catalog and search), Information Retrieval areas (such as User Profiling, Recommendation Systems, and Indexing & Search) and Machine Learning, Data Mining and Semantic Technologies, specially when applied to the above fields.

Lately, he has been seen mostly in Telefónica Global Video Unit, taking care of the recommendation engine deployed for Telefónica video services.

He has participated in and led international research projects in different European Framework Programmes. He has also been involved in international standardization activities, and for several years acted as Head of Delegation at the MPEG Committee in ISO. He is author/co-author of around 30 publications in peer-reviewed journals and conferences.

He is also an Assistant Professor at Universidad Autónoma de Madrid

Before the current position of Technology Expert, he worked (in reverse chronological order) as Technical Consultant, Division Head, Project Leader and Research Engineer. He holds a M.Sci. in Telecommunications Engineering from Universidad Politécnica de Madrid.
