HAEnv
A simulation environment for generating patient histories and evaluating health agents.
The project
HAEnv is open-source research software from Theta Health. It generates synthetic patient histories from specified underlying conditions and derives reference answers from the simulation to evaluate health agents.
My contribution
As part of my work at Theta Health, I developed patient-generation and evaluation tooling, verification checks, and the interactive demonstration. This is a team project released under the Theta Health organization.
How it works
The pipeline generates a patient history, verifies the case, exposes the information available at a specified time, and evaluates an agent’s answer. The public tools cover diagnosis, triage, medication adjustment, and follow-up interpretation.
The demo shows the synthetic patient timeline and simulation settings. These are research scenarios using synthetic data; they do not establish clinical validation.
