Research lines, ongoing projects, and open-source software
Research
Research lines, funded projects, and open-source software advancing the theory and methods of social network science.
Research Areas
Social Network Analysis & Network Science
Foundational concepts, measures, and models for studying relational structure across the social and behavioral sciences.
Statistical Network Models
ERGMs, stochastic actor-oriented models (SAOMs), and relational event models for inference on network structure and change.
Mathematical Sociology
Formal and generative models that link micro-level mechanisms to macro-level social structure.
Computational Social Science
Simulation- and data-intensive approaches that combine computation with social theory.
Network Data Science & Graph Machine Learning
Learning representations, patterns, and predictions from graph-structured data.
Methods & Open-Source Software
Reproducible tools for network analysis, including the R package netmem.
Science of Science & Knowledge
How researchers, ideas, and institutions form networks that shape the production of scientific knowledge.
Governance & Policy Networks
Inter-organizational and inter-municipal coordination in public administration and metropolitan governance.
Organizational Networks
Informal structure, collaboration, and influence within and between organizations.
Educational Networks
Relational processes in schools and educational systems, from equity to the diffusion of innovations.
Projects

The institutional complexity of metropolitan governance networks in Chile and Colombia.
Principal Investigator: Karina Arias Yurisch. Co-Principal Investigators: Karina Retamal, Alejandro Espinosa-Rada, Cristian Leyton.
Applying multilevel network analysis to the institutional framework of metropolitan environmental governance — part of the group’s broader SNA-SES (Social Networks and Socio-ecological Sustainability) research line, alongside the UC–UNSW Seed Fund (2025–2026, with Pavel Krivitsky) and prior ANID/FONDECYT Nº1220560 (2022–2025).
Responsible Investigator: Karina Arias. Principal Investigator: Alejandro Espinosa-Rada.
Social network analysis among educational actors in the Magallanes region and its influence on the diffusion of innovations in classrooms.
