My research focuses on changing structure and agency in global environmental governance (GEG). The goal is to understand the causes, state, effects and management options for fragmentation in GEG. Fragmentation implies that international politics has changed fundamentally with the proliferation of actors and agreements governing different issue areas such as climate change and biodiversity, and create governance overlaps and gaps. In my research, I strive to combine quantitative (social) network approaches (SNA) and statistics with qualitative analysis from political science, international relations and sociology.
