Pia-Johanna Schweizer has led the research group "Systemic Risks" since joining the Institute for Advanced Sustainability Studies in September 2016. The research group analyses the complex interface of science, economics, and civil society with regard to systemic risks such as climate engineering and financial risk, paying particular attention to complexity, uncertainty and ambiguity. The research group seeks to identify the "trigger points" that lead to cascading effects in various social sub-systems and will develop governance strategies for improved decision-making.
