My main research field is Computer-Supported Cooperative Work and Social Computing. My principal line of work is the study of Open Online Communities (OOC), driven by open collaboration (like Wikipedia, StackExchange or open source software projects). I usually apply a multidisciplinary perspective and follow quantitative or mixed-methods approaches.

I have more than 8 years of experience in data analytics and engineering, and I have participated in more than 20 different projects in areas such as software engineering, quality assessment, content classification, opinion mining, participatory democracy or energy efficiency. My work has been funded by Spanish and European research programs (EU-FP6, EU-FP7, Avanza, INNPACTO), public institutions (CENATIC) and private companies.
