Board of Trustees
Our Trustees are responsible for the strategic direction of IChemE. All top-level decisions are ratified by the Board. In addition, IChemE's annual budget and financial decisions are scrutinised and signed-off by the Trustees. Trustees have a joint responsibility to work together and drive the Institution forward.
