About me

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

Hi! I am Pablo Aragón, PhD candidate at the Artificial Intelligence and Machine Learning Research group – Universitat Pompeu Fabra, under the supervision of Dr. Vicenç Gómez and Dr. Andreas Kaltenbrunner. My main research interests are:

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

Since 2011 I work as a data scientist at the Digital Humanities Unit in Eurecat – Technology Centre of Catalonia (formerly the Social Media research group in Barcelona Media), where my main activity deals with retrieving, analysing and visualising Big Data from the Social Web. I focus on the study of the effects of digital platforms in citizen participatory processes as well as communication dynamics and information diffusion in the context of networked social movements.

Additionally, I actively collaborate with the Tecnopolítica research group (Internet Interdisciplinary Institute – Open University of Catalonia) in the projects:

My research activities include my services at the Program Comittee of

and the review of journals articles in

Besides research, I am teaching assistant at the Universitat Pompeu Fabra and I have co-supervised the Master thesis:

Also, I have served as invited lecturer at

Before my academic career, I worked as a data engineer designing crawlers and backend systems for social media monitoring processes in a startup company.


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