The role of the Science Advisory Committee (SAC) established by the IIASA Council in 2002, is to ensure that IIASA work continues to meet the highest standards in both scientific and policy relevant communities.
Professor Jim Hall is the fourth SAC Chair, succeeding Professor Mary Scholes of Wits University.
The SAC was established in 2002 by the IIASA Council – the governing body of the institute – and is tasked with ensuring that IIASA work continues to meet the highest standards in terms of both scientific merit and policy relevance.
The committee meets approximately once per year, or more often if required, and the SAC Chair is invited to attend Council meetings as a guest.
The Science Advisory Committee is an advisory structure constituted of independent scientists appointed by the IIASA Council with the task of providing scientific guidance and a research assurance function for IIASA. SAC reports directly to the IIASA Deputy Director General for Science and engages with the Director General, and indirectly to the Research and Engagement Committee of Council.
SAC members are appointed by the Council to three-year terms (for a maximum of six years), from a list of nominations solicited from IIASA Member Organizations, staff, and the IIASA scientific network. Members are selected based on their scientific and policy experience in the areas of IIASA research, with attention to balance regarding scientific disciplines, world regions, gender, and experience in global science-policy activities.
