What We Do




HESI Mission

At HESI, it is our mission to collaboratively identify and help to resolve global health and environmental challenges through the engagement of scientists from academia, government, industry, clinical practice, research institutes and NGOs. We achieve that in a variety of ways:

Create a collaborative environment where scientists from academia, government, industry, and NGOs come together to find solutions that improve health and environmental safety.

Encourage the development of meaningful studies that ask the right questions, structure the right framework, and develop solutions that inform decision-making by both private- and public-sector scientists.

Create a knowledge base that can be easily transferred from the laboratory or journal page to real life.

HESI Philosophy


Everyone benefits when scientists come together to find a consensus on the most pressing issues facing humans and the environment. HESI provides an open, collaborative environment where scientists from the public and private sectors work together to find solutions to global challenges. We strive to make solving complex scientific problems more efficient by providing our members with access to the best minds around the world and encouraging them to come together to solve problems. We conduct the hard, understated work of testing processes and frameworks that allow scientific data to be translated into actions that protect the environment and human health. By using HESI’s framework, other parties can ensure their research resources are being used efficiently to produce results that benefit the greater good and can be applied to practical situations. HESI serves as the moderator and facilitator for conversations between regulators and industry to help build consensus surrounding technology platforms and scientific frameworks that can be used in risk and safety assessments. We have formal partnerships with key governmental and non-governmental bodies in shared support for quality safety science.

Quick History

HESI was established in 1989 as a global branch of the International Life Sciences Institute (ILSI) (www.ilsi.org) to provide an international forum to advance the understanding of scientific issues related to human health, toxicology, risk assessment, and the environment. In 2002, HESI was recognized by the United States government as a publicly-supported, tax-exempt,  501c3 nonprofit organization, independently chartered from ILSI. In 2018, HESI became a fully independent entity and remains a global organization with program partners throughout the world.
