Samuel Martin-Gutierrez was a PostDoc at the Complexity Science Hub from May 2021 until February 2025.

He studied physics at Universidad de Valladolid and Universidad de Granada in Spain. During his master’s in complex systems at the Universidad Politécnica de Madrid, he investigated the relationship between agricultural activities and communication and mobility patterns in Senegal, using mobile phone data.

For his PhD thesis, Samuel used techniques from network and data science to analyze multiple datasets of online user behavior obtained from social contexts where polarization could arise.

His main research interest was the study of collective human behavior, which he approached from two perspectives: large-scale data-driven analysis and the development of models to reproduce the behavioral patterns found in those analyses. He was especially interested in studying the emergence of inequalities and polarization in social systems.

At CSH, Samuel mainly worked with Fariba Karimi on computational social science and network inequality.

He also collaborated with the Grupo de Sistemas Complejos (Complex Systems Group) at the Universidad Politécnica de Madrid.
