AgentMaps Popular open source library for social simulations.

Was #1 on GitHub at launch and used by hundreds of orgs around the world for simulating epidemics, markets, and other dynamics on maps. I wrote all the code by hand, pre-LLMs :)

Replication Crisis Simulation platform for DARPA's Ground Truth project.

Built to understand the replication crisis in social science: why studies in psychology, sociology, and behavioral economics so often fail to replicate, and how we can do better at modeling human behavior.
