Although health and disease are affected by both genes and environment, on average, genetics alone only explains 30–50% of their risks. Identifying the elusive environmental drivers and deciphering the connections in the exposure-disease continuum remain grand challenges in the coming decades and are the key motivations behind our work. 

The exposome encompasses life-course environmental exposures and complements the concept of the genome. Exposomics, a rapidly emerging field, helps scientists to uncover the impacts of complex mixture exposures.

At the Chung Group, we develop and utilize various tools and approaches to decode the exposome and understand the health impacts arising from our environment. We envision that our endeavors in exposomics will lead to tangible and innovative solutions that contribute to personalized intervention and a healthy and sustainable society.
