Health and Environmental Sciences Institute (HESI) (https://hesiglobal.org). HESI is a publicly supported, tax-exempt organization that provides an international forum to advance the understanding of scientific issues related to human health, toxicology, risk assessment, and the environment through the engagement of scientists from academia, government, industry, nongovernmental organizations, and other strategic partners. This HESI scientific initiative is primarily supported by in-kind contributions from public and private sector participants of time, expertise, and experimental effort. These contributions are supplemented by direct funding that largely supports program infrastructure and management that was provided by HESI's corporate sponsors.
