Who we are

Nettrek is a scientific research group focused on network research situated at Tilburg University and Jheronimus Academy of Data Science (JADS), The Netherlands. Our team members have a diverse background in statistical modeling (Bayesian and classical), artificial intelligence, and the social and behavioral sciences. We develop novel statistical and data scientific methods for social network research to better understand social network dynamics from empirical data. Our methods have been applied to learn about information sharing between employees in organizational networks, about real-time changes in communication structures during the Appollo 13 mission as a results of interventions or problems (“Houston, we have a problem!”), about drivers of violent interactions between criminal gangs, about the temporal development of social relationships between freshmen, and about classroom dynamics between children and teachers to investigate how disorder arises and dissolves, among others.


Our projects focus on diverse problems on statistical modeling of social network data such as identifying the most important drivers of temporal social interaction dynamics, learning changes about social interaction behavior network in real time, and investigating how the past affects the future using (memory) decay functions of past events, among others.

We implement our statistical and data scientific methods in free, open, and user-friendly software.
