Kenya has announced four more Ebola cases, now 7 altogether. All of these are still tied to the 40-year old man who traveled from the DRC via Uganda to Nairobi. And all of these were already in quarantine when diagnosed according to Kenya's ministry of health. www.reuters.com/business/hea...

New paper out! We combine anonymized mobility data from 11 US metropolitan areas with precinct-level electoral results to study what political environments people encounter in their daily routines. In collaboration with @marcotonin.bsky.social @estebanmoro.bsky.social and Bruno Lepri

Is the world getting more polarized? The polarization of the U.S. is worrying. But is polarization similarly bad elsewhere? What drives polarization globally, what role does social media play, and will AI make things worse? New review in @nature.com communications: www.nature.com/articles/s41...

Very excited that @bocconi.bsky.social will host IC2S2 next year in Milan. Stay tuned!!! Thanks to the organizing committee already very active @mtizzoni.bsky.social @duiliobalsamo.bsky.social @lorenzolucchini.bsky.social @deboranozza.bsky.social @Raya Muttarak @BrunoLepri

Attending #IC2S2!! Will be co-organizing a tutorial on Simulating Human Survey Responses with Large Language Models, today at 1.15PM, and presenting on Friday in the Understanding Large Language Models session, 10.45AM. Looking forward to catching up with old friends and meeting new ones!!

We have done many field experiments documenting the policy relevance of social contagion and I wholly agree that “diffusion should be part of behavioural policy making.” This paper is a valuable exploration of mechanisms involved.

Another massive jump in Ebola cases in DRC (reflecting new cases as well as "data harmonization"). Now 2,905 cases including 1,269 deaths. I find it harder every day to square the size and speed of spread of this outbreak with the lack of attention it is getting. insp.cd/sitrep-n069-...

This is really starting to pick up steam and that is not a good thing. Devastating that the US is so absent in all of this - we have a duty to help, firstly because we care to help others, secondly to help limit more widespread dissemination, including, but not limited to, the U.S.

My first PhD project is finally a paper! 🎉🥹 In 2020, we paused this work to respond to COVID-19. But as mobile phone data became largely available and key to disease modeling, that detour provided the perfect context for this paper. @bansallab.bsky.social @stefania Rubrichi @vcolizza.bsky.social

The first Ebola case has been reported today in France. Our rapid risk assessment last month showed that France consistently ranked among the European countries at highest risk of importation if an Ebola case were to arrive in Europe from the ongoing Bundibugyo outbreak.

Today is Technopanic publication day! I have many things to say about it (and I will in the next weeks) but for now: the Kindle edition costs as much as a coffee (or two espresso in Italy…), so no excuse not to grab a copy and judge for yourself. -->
