Brain Imaging Decoding visual thoughts using functional near-infrared spectroscopy.
Experiments to predict what people were visualizing using non-invasive brain imaging with some amazing people.
Hi, I'm Andrew.
I'm interested in how drugs, healthcare, justice, and scientific institutions get built, and how to build them better. I also like books like Solaris and A Month in the Country, and music like Leonard Cohen and FKJ.
Projects
Medical Justice Helping patients get justice for medical negligence with an AI-native law firm.
Drug Discovery AI for cancer drug discovery at Roivant.
Senior AI Scientist at Roivant working on molecular optimization and evals for ternary interaction predictions.

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.
