Science Advisory Committee

The role of the Science Advisory Committee (SAC), established by the IIASA Council in 2002, is to ensure that IIASA work continues to meet highest standards in both scientific and policy relevant community.

Professor Jim Hall is the fourth SAC Chair, succeeding Professor Mary Scholes of the Wits University. 

The SAC was established in 2002 by the IIASA Council – the governing body of the Institute with the main task to ensure that IIASA’s work continues to meet highest standards in both scientific merit and policy relevance.

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 has a dual reporting line. SAC directly reports 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 3-year terms (and maximum 6 years), from a list of nominations solicited from IIASA’s National Member Organizations, staff, and IIASA's scientific network. Members are selected based on their scientific and policy experience in the areas of IIASA's research, with attention to balance regarding scientific disciplines, world regions, gender, and experience in global science policy activities.  

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.

Current SAC members are:
