I have the following appointments:

• Coordinator for SLU's assessment program for Arctic/alpine landscapes (since 2017)
• Swedish representative and co-chair for the freshwater group of the Circumpolar Biodiversity Monitoring Program of the Conservation of Arctic Flora and Fauna (CAFF), the biodiversity working group of the Arctic Council (since 2010)
