AI + Earth observation to measure what changes lives—and why.

We fuse satellite imagery with modern AI to map poverty, conflict, and sustainability from 1984 to today. Then we move beyond prediction to planetary-scale causal inference—identifying what drives change, and what works.

Research Themes

🗺️

Poverty Mapping

High-resolution poverty estimates from satellite imagery. We track economic wellbeing across regions and decades where surveys cannot reach.

📊

Conflict Analysis

Automated building damage assessment and conflict monitoring. We quantify humanitarian impacts using satellite data and machine learning.

🌍

Sustainability

Environmental change detection and climate impact measurement. We connect Earth observation data to sustainable development outcomes.
