There is a study of the fascinating interplay between the cumulative effects of external exposures on our body and our genes. It is called exposomics. Learn why we need to recognize that we're exposed to hundreds or thousands of chemicals per day, and why it’s important to study that complexity. Featured experts are Dr. Konstantinos Lazaridis, Director of Center for Individualized Medicine at Mayo Clinic; and Dr. Gary Miller, Vice Dean of Research Strategy and Innovation of Mailman School of Public Health and Director of the Center for Innovative Exposomics at Columbia University.
