Projects

I enjoy learning how people use data to understand places on Earth and make decisions about them. I build small tools and prototypes to explore these ideas, mainly around geospatial interfaces, Earth observation, AI, and human decision-making. These notes are a record of what I tried and what I noticed along the way.

A question I keep returning to

Spatial Understanding and Decision-Making

How can spatial data representations support human understanding and spatial decision-making?

Maps, satellite imagery, sensors, and models let us learn about distant places and changes outside our direct view. I'm interested in how these representations shape what people notice, understand, and decide.
