Excited to share our new research demo, where you can freely traverse the world of Bluesky through 20,000 interconnected trails, spanning “analysis of fictional tropes” to “rotisserie chicken” to “zoning and land use policy.”
Try it out, and let us know what you think!
Urban Data
New research is offering new insight on how Americans move — all the way to the neighborhood level.
A new dataset, MIGRATE, maps annual moves with 4,600‑times more detail than standard public data, revealing patterns hidden in county‑level reporting:

New in Nature Health: how might we move towards a world in which race is not used in clinical algorithms? We need (1) careful comparison of race-aware and race-neutral algorithms and (2) systemic efforts to address underlying disparities.
New paper! The Linear Representation Hypothesis is a powerful intuition for how language models work, but lacks formalization. We give a mathematical framework in which we can ask and answer a basic question: how many features can be stored under the hypothesis? 🧵 arxiv.org/abs/2602.11246

We made traversle.io, a new daily word game! The goal is to traverse from a start word to a target word through a network of related words. (Our motivating question: is it possible to construct a network that allows human navigation?)

Excited to see MIGRATE recognized in the IPUMS awards! Huge thanks to @emmapierson.bsky.social, @nkgarg.bsky.social, and our coauthors. Our work primarily aims to make spatiotemporal data more trustworthy and accessible to researchers, just like IPUMS. Read the paper to request data access!
Had a great time presenting our work on building MIGRATE–a new dataset of US migration–at the @geographers.bsky.social AAG Annual Meeting today. Happy to also share that we received an AAG student paper award for this work!!!
Come chat if you are at #AAG26 this week.

Excited to share #ICML2026 paper from my internship @ Google DeepMind!
AI models are deployed globally, but AI safety datasets are largely geographically homogenous. What is the impact of culture on AI safety ratings? Is there any impact beyond standard demographics like age, gender, and ethnicity?

Can we regain freedom of movement on social media? Browse Bluesky via interconnected trails.
IPUMS Spatial Student Award is a tie!
@gsagostini.bsky.social for "Inferring Fine-Grained Migration Patterns Across the United States." (www.nature.com/articles/s41...)
This study releases a very high-resolution migration dataset that reveals trends that shape daily life: rising moves into high-income neighborhoods, racial gaps in upward mobility, and wildfire-driven...
