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
(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.
Understanding complex socio-technical systems
My long-term research goal is to leverage innovative solutions from big data analytics
to improve our understanding of complex sociotechnical systems in which users,
developers, businesses and other stakeholders collaborate and compete to create valuable
knowledge and products.
To this aim, I work on the design and integration of methodologies, processes and
computational systems (hardware and software) for big data analysis in different
application domains: peer production Internet communities
(Wikipedia, Stack Exchange),
software engineering (FLOSS),
online learning, energy efficiency, content classification and opinion mining. I follow
a multidisciplinary approach, integrating elements from a variety of disciplines such
as computer science, statistics, sociology or economy.
