🚨Out today in @Nature our new paper uses deep learning to map four decades of global human migration.

By building the first comprehensive dataset of global annual flows (1990-2023), we reveal that migration has nearly tripled since 2000.

Excited to FINALLY release toughest+most rewarding paper I've worked on...

The internet says that you get a doctoral sword when you finish your PhD in Finland. Well, when you conclude a PhD in France, you may get a giant croissant (if you have the right friends, that is). A big thank you to my friends and colleagues from @PSEinfo ♥️🥐
