José Luis Molina, Jürgen Lerner and Javier Anton Pelayo
(2025; preprint)

Analysing Martí de Burguès (1756-1809)’s personal network, using relational hyper-event models (RHEM), reconstructs the social and cultural structures from his time. It highlights the relationship between relational structures and the understanding of sociocultural phenomena.

Name generators in egocentric network research: a comparative analysis of three approaches

SocArXiV (2025; preprint)

This article explores systematically how the choice of name generator—whether to elicit a fixed number of alters or to allow a variable number—impacts the structural properties of ego networks, shedding light on an ongoing debate about the best approach for collecting social network data.

Towards a General Method to Classify Personal Network Structures
Miguel Á. González-Casado, Gladis Gonzales, José Luis Molina, and Angel Sánchez
Social Networks 78, 265-278 (2024)

Recent publication from the group in which we establish the bases to classify personal network structures, showing that there are only a few types possible and interpret those few types.

Evidence of equilibrium dynamics in human social networks evolving in time
Miguel A. González-Casado, Andreia Sofia Teixeira, and Angel Sánchez (2024; preprint)

Based on interactions of 900 individuals over four years, the authors find structural stability in social networks, comparable to the concept of equilibrium in statistical physics.

Indirect social influence and diffusion of innovations: An experimental approach
Manuel Miranda, María Pereda, Angel Sánchez and Ernesto Estrada
PNAS Nexus, 3, 10,(2024)

Under peer pressure beyond our directly connected friends: A mathematical model for innovation diffusion, based on experimental outcomes, assigns roles to direct and indirect neighbors. It shows that members of our social group have a considerable influence on adaption, decaying with social distance.

Structural measures of personal networks predict migrants’ cultural backgrounds. An explanation from Grid/Group theory
José Luis Molina, Juan Ozaita, Ignacio Tamarit, Angel Sánchez, Christopher McCarty, and H. Russell Bernard
PNAS Nexus 1, pgac195 (2022)

The paper that started it all: the three PIs and their team analyzed data from migrants and demonstrated that there is mutual information between personal networks and culture.
