AI for legal epidemiology

Last updated: December 31, 2025

Epidemiology starts with data

Overview

Legal epidemiology—understanding the effects of laws on health—requires an understanding of what the law is. But laws are spread across jurisdictions and different levels of government, and are framed in technical language that can be difficult to encode for analysis. Since 2024, I have been working with collaborators on a project to apply large language models and modern retrieval methods to make encoding of laws easier, focusing on the municipal codes and ordinances of hundreds of citites in the United States. This is part of a broader interest in making law more accessible.

Project milestones are logged as short updates in the Projects log.
