Fantastic workshop on Monday in Amsterdam. Productive talks, strengthen connections, exciting next steps for the international population-scale network research community

Our review on multilayer network science is out on the arXiv. Thanks to all collaborators of the AccelNet MultiNet project, great working with you all 🙏 @alexvespi.bsky.social @ymoreno.bsky.social @lordgrilo.bsky.social @anduviera.bsky.social @baronca.bsky.social arxiv.org/abs/2511.23371

We welcome @anmen.bsky.social as a new postdoctoral researcher at Uppsala University, Dept. of Information Technology, and as a new member of the InfoLab.

New paper in Science Advances: “Intersectional inequalities in social ties” 🔗 www.science.org/doi/10.1126/... A quantitative framework to measure how inequalities emerge in social networks when multiple identities intersect. #SocialNetworks #Inequality #Intersectionality #ComplexSystems

Congratulations to our @dvladek.bsky.social for being appointed Docent in Computer Science!

How fair are the algorithms that decide who gets information online? Our new paper in PNAS Nexus shows that maximization algorithms, the ones used to pick “influencers” in social networks, unintentionally deepen inequality. 🧠 Sekara, Dotu, Cebrian, Moro & García-Herranz 🔗 doi.org/10.1093/pnas...

MOUFLON: Multi-group Modularity-based Fairness-aware Community Detection https://arxiv.org/abs/2510.12348 In this paper, we propose MOUFLON, a fairness-aware, modularity-based community detection method that allows adjusting the importance of partition quality over fairness outcomes. MOUFLON ...📈🤖

Nearly twenty years after the first igraph release, igraph 1.0 has finally arrived! 🎉 This release focuses on providing a stable and more consistent interface that users and downstream maintainers can rely on with confidence. For more detail, see igraph.org/2025/09/20/i...

Our new study provides the first large-scale look at how collective action is expressed in spoken digital discourse, using #BlackLivesMatter as a case study. Many thanks to @ariannapera.bsky.social @dvladek.bsky.social @lajello.bsky.social for the collab Check it out: arxiv.org/abs/2509.13197

I will not stop using my em dashes out of fear of a reviewer accusing me of using AI!

📢Take a breath, you have extra days to finish! Due to technical issues with @openreviewnet this week, we’ve extended all deadlines by 2 weeks. 🗓️New deadline for abstracts: Sept 19, 23:59 AoE 📷 More info: netscix2026.github.io @MLuczak @ProfMSmall @droneale @danielapaolotti

Population-Scale Network Embeddings Expose Educational Divides in Network Structure Related to Right-Wing Populist Voting https://arxiv.org/abs/2508.21236 Administrative registry data can be used to construct population-scale networks whose ties reflect shared social contexts between persons....📈🤖

Final year PhD students, I know you’re desperately trying to finish experiments/revisions/submissions/write a thesis & just survive - but please spare a few minutes to apply to your dream postdoc labs. It easily takes A YEAR from first contact, even if everything goes to plan on both sides.

Our article on population-scale networks of social opportunities constructed from administrative data is now available online: www.nature.com/articles/s41....

🧮 ~8M nodes, 330M relationships across family, household, school & work. 🇸🇪 We constructed a multilayer population-scale network for Sweden, capturing distinct features of the country. 📝 doi.org/10.1038/s415... cc: @ingakwoh.bsky.social @matmagnani.bsky.social ++

Catching up on emails after week away from office really highlights just how many predatory journal invites I receive (even though I routinely block them). #academicsky

Summer CV-worthy math project (finishing balatro) complete. Now to finally update my website

So glad for the support I received🙏🏻 I met so many interesting people, had fruitful discussions and so much fun! Special thank to my supervisors @dvladek.bsky.social @calikus.bsky.social , to my amazing colleagues @uuinfolab.bsky.social and … [comments]

It‘s a wrap! Man, what an experience. I’m 150% exhausted, but 200% happy! It was an honor hosting #IC2S2 2025 in Norrköping with phenomenal weather for so many lovely people! I can’t wait to see you all again! Many thanks to all participants, keynote speakers, and helpers! ❤️

Happy to be part of this work and seeing it being presented here in Sweden!

No better place than a Swedish #ic2s2 to present our population-scale network of Sweden! 🇸🇪 Very grateful to discuss ideas and challenges with colleagues (future collaborators?) working with similar data. You can find our preprint here: doi.org/10.31235/osf...

We did a thing, and we are presenting it today at the @ic2s2.bsky.social #IC2S2 poster session: A model to study Manipulative Language. Work led by @dilettagoglia.bsky.social, in collaboration with @calikus.bsky.social and myself. Find Diletta at poster #26.

@uuinfolab.bsky.social @ #ic2s2

My friends from Uppsala are going strong — check their presentations out, great stuff! #ic2s2 @dilettagoglia.bsky.social @giorgospanay.bsky.social @ingakwoh.bsky.social @dvladek.bsky.social et al.

This week we are at #ICWSM, with @giorgospanay.bsky.social talking about representational fairness in graph community detection.

The challenges of measuring representational fairness of graph community detection algorithms by @giorgospanay.bsky.social at DETOX #ICWSM.

Kicking off #ICWSM with the DETOX workshop and @maxfalken.bsky.social’s keynote on why the Web is not a set of siloed platforms and why we should not study it as such. Shows why deplatforming doesn’t work exactly as we expect and why large online platforms are plagued by affective polarization

Hello Copenhagen! This week I will be at @icwsm.bsky.social and the DETOX workshop. Looking forward to meeting new colleagues and old friends!

I'll be at #ICWSM 2025 next week to present our paper about Bluesky Starter Packs. For the occasion, I've created a Starter Pack with all the organizers, speakers, and authors of this year I could find on Bluesky! Link: go.bsky.app/GDkQ3y7 Let me know if I missed anyone!

Our new preprint on detecting coordination on TikTok 👇🏻

New preprint: we delve into the challenges of finding coordination in short-video platforms In this work led by @ingakwoh.bsky.social with @matmagnani.bsky.social and Alexandra Segerberg we propose a multimodal network-based method to identify possible coordination in TikTok arxiv.org/pdf/2506.05868

🎉 🚀 #SICSS-IAS is officially underway! We’re excited to kick off two weeks of learning, coding, and collaboration with a brilliant new cohort of aspiring computational social scientists.

Ironic that transit from #NetSci2025 @netsciconf.bsky.social is disrupted due to failure of a high-betweenness node.

Big day yesterday at InfoLab :-)

Multilayer network of the day. From: LA Brown, Diffusion Dynamics (1968).

1/ The US government has ordered the Swedish city of Stockholm to end its diversity, inclusivity and equality (DEI) programmes within 10 days. The city authorities say the demand is "bizarre" and they won't be complying. ⬇️

Back home after a month-long AccelNet-MultiNet exchange at IU Bloomington-- time really flies by! Thank you @santof.bsky.social, and to everybody at CNetS for a wonderful time there!
