Who is HESI?
The Health and Environmental Sciences Institute (HESI) is an independently incorporated 501c3 nonprofit organization. HESI’s offices are located in Washington, DC but we operate with members and program partners throughout the world.

What is HESI’s mission?
HESI’s mission is to identify health and environmental concerns and create scientific solutions to support a healthier, more sustainable world.

How does HESI achieve its mission?
HESI engages scientists from academia, government, industry, and other research institutes to design and implement programs that generate new knowledge in the areas of toxicology and risk science.

What does HESI do?
HESI conducts, organizes, and/or supports, original laboratory research; workshops; conferences; literature reviews; the development and analysis of databases; and many other scientific activities. HESI makes the outcomes of these activities available to the scientific community and the public through peer-reviewed journals; monographs; scientific symposia and posters; and other print- and web-based publications.

How does HESI stay current on emerging scientific issues?
HESI identifies new scientific issues throughout the year. For more information on how to submit a project idea, visit this page. Anyone is welcome and encouraged to propose a topic. Topics are prioritized by relevance to HESI’s mission; potential for scientific impact; uniqueness; and achievability.

How is HESI funded?
 HESI’s scientific initiatives are primarily supported by the in-kind contributions (from public and private sector participants) of time, expertise, and experimental effort. These contributions are supplemented by grants from governments and foundations as well as direct funding (that primarily supports program infrastructure and management) provided primarily by HESI’s corporate sponsors. 

Who governs HESI?
HESI is governed by a Board of Trustees, which is required to have an equal or greater number of trustees from academia or other public institution to those from HESI’s corporate supporters. This rule is in place to ensure a public-private balance of scientific perspective and experience.

The Board of Trustees is responsible for setting and enforcing organizational policies; setting scientific direction; and ensuring scientific integrity and financial transparency.

Who staffs HESI?
HESI’s long-term scientific programs, organizational strategies, and day-to-day operations are managed by a dedicated group of talented scientific professionals. With decades of experience and credentials ranging from master’s degrees to specialized PhDs, HESI staff is integral to its ongoing success.

Does HESI lobby?
HESI does not directly represent any of the sectors or entities that participate with HESI and does not lobby on their behalf. HESI’s code of ethics strictly prohibits any form of lobby activity. While HESI advocates the use of science in making decisions that affect human and environmental health, it does not make policy recommendations or seek to influence legislative outcomes toward a particular decision. 

Are there any examples of how HESI science has made the world healthier or more sustainable?
There are many examples where HESI’s work has led to improved scientific data and approaches, which in turn improves human and environmental health. A few examples are provided on this page.
