My name is Alejandro Espinosa-Rada. I am an Assistant Professor in the Department of Sociology at the Pontifical Catholic University of Chile and a Visiting Professor at the Centre for Sociological Research at KU Leuven in Belgium. Previously, I was a Postdoctoral Researcher and Lecturer at the Social Networks Lab at ETH Zurich, and I completed my PhD in Sociology at the Mitchell Centre for Social Network Analysis at the University of Manchester. 

My research focuses on how social relations generate and sustain collective forms such as organizations, scientific communities, and systems of knowledge production. I am particularly interested in how relational structures shape coordination, inequality, and institutional dynamics across different social contexts. Within this research program, I also work on the development of formal and statistical network models to represent and analyse these processes. This work connects the sociology of organizations, the sociology of science and knowledge, group dynamics, and social network analysis.

I am also the developer and maintainer of the CRAN R package netmem: Network Measures using Matrices, which provides tools for matrix-based network analysis and measurement.

I serve as Director of the Chilean Society for Social Network Science (CHISOCNET), Co-Editor-in-Chief of Connections and Scientific Communications Editor of the journal Network Science

You can also check out Knitting Networks, the Social Network Science podcast, which I co-host with Francisca Ortiz. Episodes are available in Spanish and English, and the podcast is endorsed by the International Network for Social Network Analysis (INSNA).

In my spare time, I enjoy practising Capoeira and playing the keyboard (progressive rock).
