Interviewee: Melanie Pearson, Ph.D.

In our second episode exploring the exposome, we’ll learn how incorporating community perspectives into the exposome definition could help researchers better understand the totality of lifetime exposures and improve human health.

The Exposome and Health (Part 2)

The exposome is a growing area of research that aims to assess all the environmental factors a person is exposed to throughout their life and how those exposures affect health. Some scientists are calling for an expansion of this definition — which primarily focuses on an individual’s chemical exposures — to include the perspectives of communities facing environmental health challenges.

In the second installment of our two-part series focused on the exposome, Melanie Pearson, Ph.D., discusses how bringing the community voice into the exposome could help researchers better capture the totality of lifetime exposures and improve human health. To learn more about exposome research, check out the first episode in the series.
