I've defended my PhD 🎓🙂

Huge thanks to @nuriaoliver.com for her guidance over these years and to the committee @ccattuto.bsky.social , Isabel Valera, and G. González Serrano for their time, insights, and an inspiring discussion 🙏

Excited for what's coming next!

No to simplification of EU digital laws

Weakening the AI Act would undermine accountability, the protection of society and workers and bring legal uncertainty

I have co-signed the letter led by @cdteu.bsky.social 👇🏼

⏰ Today, CDT Europe, together with 51 experts, academics & civil society organisations, sent an open letter to the European Commission to express our concerns regarding the forthcoming Digital Simplification package, which could include revisiting the AI Act.

👇🏻 Read the full letter on our website:
Open Joint Letter against the Delaying and Reopening of the AI Act

The Code of Practice is out. I co-wrote the Safety & Security Chapter, which is an implementation tool to help frontier AI companies comply with the EU AI Act in a lean but effective way. I am proud of the result!

A huge milestone was achieved today in the EU towards our common understanding of risks in the online world. If you are a researcher interested in studying societal risks related to very large online platforms and search engines, this is for you!

Needing a permanent doi was a forcing function to revisit this article on Transformers and Graph Neural Networks: arxiv.org/abs/2506.22084

This is (very) old news, so what's new?

Had a great time presenting our work at @icwsm.bsky.social on measuring and mitigating structural social capital disparities in social networks 🕸️

Really appreciated the thoughtful feedback and the chance to connect with such an amazing community!

This paper reflects my and @federico-errica.bsky.social's thoughts on some current GNNs issues (like OSM/OSQ) after spending some time working on them. We also tried to capture concerns that we've seen echoed by parts of the community.

P.S. I thought I had all these issues figured out too 😅

I've recently put together a "Fairness FAQ": tinyurl.com/fairness-faq. If you work in non-fairness ML and you've heard about fairness, perhaps you've wondered things like what the best definitions of fairness are, and whether we can train algorithms that optimize for it.

Have you ever been curious to try Causal Normalizing Flows for your project but found them intimidating? Say no more 😜

I just released a small library to easily implement and use causal-flows:

"Urban Highways Are Barriers to Social Ties" out on PNAS!
The 1st large-scale measure of how highways weaken social connections between the communities they separate. This barrier effect is strong in the 50 largest US cities--especially for low-income Black communities.
