Genes load the gun. Exposures pull the trigger.

A lifetime of exposures shapes your health: infections, pollution, stress, and thousands more. Together they are your exposome, and it can hold the answer to why you got sick.

Tell us your story.

We hunt for signals.

EXPIN searches your story for patterns of exposures and disease that are backed in the research and environmental data.
