IIASA is proud to announce that no less than 32 researchers and alumni affiliated with the institute have been included in the 2023 Research.com Top Scientists ranking in various areas of expertise.

Research.com, a data-driven platform for scientists that uses machine learning and big data analytics, compiles annual rankings of the best scholars in a variety of academic areas. The areas in which IIASA scientists achieved recognition include biology and biochemistry, Earth science, ecology and evolution, engineering and technology, environmental sciences, and social sciences and humanities. Two IIASA affiliated researchers were also included in the category for rising stars.

The rankings are formulated through a meticulous evaluation of thousands of profiles on Google Scholar and Microsoft Academic Graph. The most recent rankings were compiled using bibliometric data gathered on 21 December 2022. This data was consolidated from various academic sources and citation-based metrics. Additional factors considered for the rankings include the frequency of scholarly publications within a specific field of study, as well as the scholars' notable awards and accomplishments.

The following IIASA researchers and alumni made the list, with some included in more than one area:

Biology and biochemistry:
Keywan Riahi, Energy, Climate, and Environment Program Director

“It is very reassuring that IIASA is doing so well in this as well as in other recent rankings. For its comparatively small size it seems to have great impact. This is even more significant in light of the inter-disciplinary and trans-disciplinary nature of IIASA research that is typically more difficult to place in good journals than strictly disciplinary research,” concludes IIASA Interim Deputy Director General for Science, Wolfgang Lutz.

A reliable food supply in West Africa requires smarter planning for low-yield events

Sustainable Development Goal 2 (SDG 2) aims to create a world free of hunger. Africa is not making enough progress towards achieving this target with about 20% of the population experiencing ongoing hunger. In a new study, IIASA researchers developed a model to demonstrate how the reliability of food supply in West Africa can be enhanced in a cost-effective way by accounting for low-yield events.

Prosocial preferences can provide better risk management for smallholder farming communities amid rising climate risks

Research conducted by scientists from IIASA and Princeton University suggests that a combination of insurance subsidies and policies that promote “prosocial preferences” ― decision-making preferences that account for community wellbeing ― can help facilitate optimal climate risk management and reduce economic losses.
