It's been a while, but I am happy to share that my PhD dissertation is finally available online! 🎉

Not only it contains most of my work, but there is plenty of brand new content:

It's great to see growing interest in safety/alignment, but we often miss the social context.

Come to our @woahworkshop.bsky.social Friday to dive deeper into safe safety research!
