I'm a post-doctoral research fellow at the Applied Intelligence Research Centre of the Dublin Institute of Technology, where I'm working on the CeADAR project. My main research interests revolve around text mining, natural language processing, and social computing. My recent research has focused on mining social media for news and events, more specifically on aspects such as curation, verification, and classification of information posted by citizen journalists.
Before, I was a post-doctoral researcher at the City University of New York. Prior to that, I was a research fellow at the National Distance Learning University (UNED) in Madrid, where I obtained the PhD degree in Computer Science in 2011 with the thesis titled "Harnessing Folksonomies for Resource Classification".
If you're a researcher and/or love playing with data, you might be interested in the datasets we released recently: a large-scale collection of categorized tweets and a large-scale social-tagging dataset.
