I am a researcher in Multimedia Information Retrieval and Multimedia Analysis. My specific research interests and experience cover a number of areas, including: multimedia information retrieval; content-based and metadata-based multimedia classification; analysis of multimedia user search behavior; building test corpora for various multimedia classification/retrieval tasks; organizing personal media collections (including person recognition) using a combination of content-based and metadata-based analysis; sentiment analysis of online text documents; microblog retrieval; geographic information retrieval; social network analysis; analysis of personal lifelog data; and computational aesthetics.

I currently work in Yahoo Labs, Barcelona, principally on problems related to Image Search and Classification.
