HESI is governed by the Board of Trustees, comprised of 16 representatives from the public sector and 15 representatives from the private sector.  The Board provides scientific, strategic, and financial oversight for the organization.  The HESI Assembly, compromised of public and private sector scientists from HESI’s scientific committees, Trustees, and HESI Emerging Issue Committee Science Advisors, elects the governing Trustees and provides input on new scientific and strategic directions for the organization.
