Research
At the Society Complexity and Data Science Laboratory (CDCS Lab), our primary objective is to harness the power of data science to tackle a diverse array of challenges. These range from understanding the spread of information on social media platforms to developing models for epidemic outbreaks, and analyzing mobility trends.
We firmly believe in the synergy of network science and complex systems, utilizing this blend to construct mathematical models of intricate dynamics. It's through this integrated approach that we unravel large-scale, pivotal phenomena.

The drivers of online polarization: fitting models to data
Online users often form echo chambers within polarized groups, reinforcing shared narratives. This phenomenon arises from human biases in information consumption and personalized recommendations by feed algorithms. While previous studies have explored these dynamics using opinion dynamic models, empirical validation and qualitative analysis have been limited. This work proposes a method to numerically compare simulated opinion distributions with real social media data. We develop an opinion dynamic model that considers the interplay between human and algorithmic factors, validated against diverse social media platforms. By providing a synthetic description of social media characteristics, our research contributes to refining feed algorithms and mitigating extreme polarization's detrimental effects on online discourse.
