Metabolomics in epidemiologic research: challenges and opportunities for early-career epidemiologists.

BACKGROUND

The application of metabolomics to epidemiologic studies is increasing.

AIM OF REVIEW

Here, we describe the challenges and opportunities facing early-career epidemiologists aiming to apply metabolomics to their research.

KEY SCIENTIFIC CONCEPTS OF REVIEW

Many challenges inherent to metabolomics may provide early-career epidemiologists with the opportunity to play a pivotal role in answering critical methodological questions and moving the field forward. Although generating large-scale high-quality metabolomics data can be challenging, data can be accessed through public databases, collaboration with senior researchers or participation within interest groups. Such efforts may also assist with obtaining funding, provide knowledge on training resources, and help early-career epidemiologists to publish in the field of metabolomics.
