About me

The following quote by Jon Kleinberg defines accurately my career aim:

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

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 emerging grassroot movements.

Additionally, I actively collaborate with the “Networks, Social Movements and Technopolitics” research group (Internet Interdisciplinary Institute – Open University of Catalonia) in the projects:

My research activities include my services at the

and the review of journals articles in

Besides research, I am also teaching assistant at the Universitat Pompeu Fabra and I have served as invited lecturer at the Universitat Oberta de Catalunya, the Universidad Autónoma de Barcelona, the Universidad Autónoma de Madrid, the Col·legi de Periodistes de Catalunya, the Instituto Tecnológico de Monterrey, the Universidad Autónoma de Querétaro and Medialab Prado.

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 Network of Excellence Internet Science Summer School organised by the Oxford Internet Institute.
