Verified at Stockholm University

Passionate about economic research that draws on creative data work. From register data workflows and scraping tools to satellite-based models of development.

About

I’m a PhD student in Economics at Stockholm University, interested in development, labor, and political economics. I prefer working with complex and unconventional data and focus on designing workflows that make it usable for serious empirical research.

I’ve developed tools used by researchers and institutions, including RegiStream, an open-source framework for register data workflows, and a geospatial classifier that detects rural road upgrades in satellite imagery to measure development in remote areas.

I’m interested in research that pushes the boundaries of what can be measured. I like working on problems that require technical creativity, whether that means designing new labeling strategies, automating workflows, or building tools that help researchers ask better questions.
