The Microbiome

March 2, 2015

Expert: Lisa Hebling Chadwick, Ph.D.

The collection of microbes living on and inside of our bodies—the microbiome—impacts our health in myriad ways. Because the microbiome is our body's first point of contact with the environment, these microbes may even affect how we are exposed to some environmental chemicals. In this podcast, we hear about studies that are underway to assess the relationships between the environment, the microbiome, and human health.

Lisa Hebling Chadwick, Ph.D., is a Health Scientist Administrator at the National Institute of Environmental Health Sciences. Chadwick is one of the program directors of the NIH Roadmap Epigenomics Program and is one of the scientific contacts for NIEHS-funded epigenetics studies. She also directs extramural research programs in microbiome/environment interaction, transgenerational inheritance, and other areas to understand how environmental exposures affect our health. She represents NIEHS in a number of trans-NIH programs, including the Human Microbiome Project. Chadwick sees the microbiome as an exciting new area for environmental health research given the microbiome’s interface between us and the environment.
