About me

“I think of myself as a computer scientist who is interested in social questions.” – Jon Kleinberg

Hi! I am Pablo Aragón, doctoral researcher at the Artificial Intelligence and Machine Learning research group in Universitat Pompeu Fabra. My research focuses on the effects of digital platforms in citizen participatory processes as well as the online network structures of grassroots movements and political parties. I am particularly interested in:

  • Computational Social Science,
  • Social Systems,
  • Technopolitics,
  • Digital Democracy,
  • Social Network Analysis.

Since 2011, I work as a data scientist at the Big Data & Data Science Unit in Eurecat, Centre Tecnològic de Catalunya (formerly known as Barcelona Media), where my main activity deals with understanding social phenomena through the analysis of data from the Internet. I was also a visiting scholar at the Oxford Internet Institute (University of Oxford) in 2018 and I actively collaborate with:

These collaborations extend the work done as a co-founder member of the research network DatAnalysis15M (book here, free content here). My research activities include my services at the Program Comittee of

and the review of journals articles in

I have served as teaching assistant of the Discrete Mathematics course at Universitat Pompeu Fabra and co-supervised the MSc thesis:

I have also served as invited lecturer at

Prior to my academic career I worked for two years as a data engineer designing backend systems for social media monitoring processes in a startup company.


I am currently pursuing a PhD in Information and Communication Technologies at the Universitat Pompeu Fabra. I obtained a MSc in Artificial Intelligence at the Universidad Nacional de Educación a Distancia – UNED in 2016, and a BSc+MSc in Computer Science & Engineering at the Universidad de Zaragoza in 2010, which included a full year as an exchange student at Luleå Tekniska Universitet (Sweden). I also attended the 1st Summer School on Methods for Computational Social Science and the 1st Summer School of the Network of Excellence in Internet Science.
