3/n Our data: Chilean astronomers (2013–2015)
🔧 Method: Relational Hyperevent Model (captures group-based events like coauthoring and citing)
💡 Key insight: Coherent groups of coauthors are more likely to be co-cited together — social structure reinforces cognitive links.
November 3, 2025 at 1:51 PM
2/n We ask: Why do researchers cite what they cite?
Beyond content relevance, we consider how social ties (coauthorship) and cognitive continuity shape citation choices.
Think of citation as the tip of a longer collaborative and intellectual process.

1/n The before mentioned paper uses a Group-Oriented Relational Hyperevent Model to explore how collaboration networks shape citation behavior among researchers.
Title: “Socio-cognitive networks between researchers”

3/6 While at ETH Zürich, I also had the opportunity to collaborate on earlier projects regarding influence processes and to discuss the survey we’re developing for my current project—one inspired by the Student Life Study @socialnetworkslab.bsky.social

2/6 As part of my project "Isolation and Groups Among Students" (FONDECYT Nº3250037, 2025–2027), I visited the Social Networks Lab at ETH Zürich to work on how to investigate identification within informal student groups. @socialnetworkslab.bsky.social

8/n Sunday was the final day of presentations.
Already feeling inspired to dive back into my research — energized and ready for even more network projects!
See you all next year! 🌐

7/n Saturday, I had the pleasure of chairing a wonderful session on scientific collaboration networks.
@franciscaortizruiz.bsky.social also presented one of our ongoing projects about a community center, in collaboration with @mirandalubbers.bsky.social

6/n On Friday, I presented our ongoing research on collaboration in sustainability science, using multilayer networks to explore how research centers operate. This is part of the sna-ses.shinyapps.io/SSMviewer/ project! (Julien Vanhulst) www.aespinosarada.com

5/n Then came the ChiSocNet gathering, where we caught up with the Chilean community working on networks @chisocnet.bsky.social @networkspodcast.bsky.social
The Simmel Award was presented, and in the evening, I had dinner with members of my second academic home — the SN Lab Zurich. @ethz.ch

4/n Wednesday marked the start of paper presentations and included a dinner with members of one of my former academic homes — the Mitchell Center for SNA @mitchellsna.bsky.social
Great seeing you, Mitchellers!

3/n On Tuesday, I had the opportunity to teach about the origins and history of the social network perspective.
We explored the “prehistory” of networks all the way to the current state of the art, through scientometric studies. @insna.bsky.social #socialnetworks
June 29, 2025 at 11:00 PM
2/n On Monday, I had the chance to attend two workshops on advanced network statistics — one on statistical models for longitudinal networks, and another on using C++ to program new effects in SAOMs. #saom #dynam #ergm #rem

1/n 🚨 Just out in Social Networks!
Our new paper (w/ Jürgen Lerner & @corneliusfritz.bsky.social) uses a Group-Oriented Relational Hyperevent Model to explore how collaboration networks shape citation behavior among researchers.
