Bravissima, Elisa 👏👏

The UC3M campus

Super happy to share that, after two great years @chub-fbk.bsky.social, I've just joined @uc3m.es and the GISC as an assistant prof in applied maths :)))

Siena, science, and so much inspiration.
Delighted to present my research on news media analysis at #CCS2025 Computational Social Science satellite.

Viva Italia! 🇮🇹

Wide coverage of social media and disinformation analysis yesterday from our lab at the @css-conference.bsky.social, with four talks presenting our works associate to the European projects #AI4TRUST #AICODE_EU #HATEDEMICS

New pre-print out ! Work led by @eleandre.bsky.social, in collaboration with M. Napolitano and @ricgallotti.bsky.social. Using Foursquare data from Bologna, we find that the distribution of POIs follows a clear power-law pattern at the city scale. To explain this, we introduce a framework where ...

Finishing the social media session, @tlouf.bsky.social explores Telegram as a weighted, directed temporal network. His methodology reveals clustering, burstiness, and assortativity, all of them phenomena that are relevant when building reliable agent-based models.

Just me pointing at prioritized communities at @css-conference.bsky.social.
Great journey, so far. 🍉

@chub-fbk.bsky.social @csaalto.bsky.social

Thrilled to share that I just gave my first-ever scientific conference talk at @css-conference.bsky.social!

I presented our work "MarkedTemporalPointProcesses for simulating and capturing coordinated behaviour" on enhancing disinformation detection.

Huge thanks to my supervisors and the audiance!☀️

If you're at #CCS25 and are interested in human mobility and inequalities, at 11:30 in Room 149 I will talk of experienced segregation. This is a work we started at the @complexity72h.bsky.social workshop last year.
Take a look at the preprint and see you there 🙂

#CCS2025

Great energy at the poster session today! It was a pleasure to be part of it presenting our work "How to design a collection strategy for monitoring disinformation and hate speech in Telegram".

Excited for round two tomorrow – see you all there! ☀️

Yesterday was our first day at @css-conference.bsky.social
in Siena 🇮🇹. We presented on Telegram data collection @elisamurators.bsky.social , city growth @ulyssemarquis.bsky.social and urban traffic (Alberto Amaduzzi). Excited for 5 more talks today! #CCS2025

So excited to see this come together! 🎉

Our latest study explores the interplay between science and misinformation in public debates during COVID-19 🔍 arxiv.org/abs/2507.01481

👇Take a look

Mapping the interaction between science and misinformation in COVID-19 tweets. Publication from @luzuzek.bsky.social, Juan Pablo Bascur, @annabertani.bsky.social, @ricgallotti.bsky.social. This project is supported by European Media and Information Fund. Abstract: During the COVID-19 pandemic, scientific understanding related to the topic evolved rapidly. Along with scientific information being discussed widely, a large circulation of false information, labelled an infodemic by the WHO, emerged. Here, we study the interaction between misinformation and science on Twitter (now X) during the COVID-19 pandemic. We built a comprehensive database of 407M COVID-19 related tweets and classified the reliability of URLs in the tweets based on Media Bias/Fact Check. In addition, we use Altmetric data to see whether a tweet refers to a scientific publication. We find that many users find that many users share both scientific and unreliable content; out of the 1.2M users who share science, also share unreliable content. Publications that are more frequently shared by users who also share unreliable content are more likely to be preprints, slightly more often retracted, have fewer citations, and are published in lower-impact journals on average. Our findings suggest that misinformation is not related to a ``deficit'' of science. In addition, our findings raise some critical questions about certain open science practices and their potential for misuse. Given the fundamental opposition between science and misinformation, our findings highlight the necessity for proactive scientific engagement on social media platforms to counter false narratives during global crises.

New preprint! 🚨

We study the interaction between misinformation and science on Twitter during COVID-19 based on ~407M tweets. Both science and misinformation featured prominently during the pandemic, but the interaction between the two has not been studied on this scale before.
