About me


I am a hydrologist that got my PhD in Nov 2017 from the Dep. of Physcial Geography here at Stockholm University. I am currently working as a post doc within the research unit for Hydrology, Water resources, and Permafrost at the department, and at Wageningen Univerisity & Research/Utrecht University, on a mobility grant from FORMAS (between 2019-2022). The project is titled: Water quality impacts water scarcity - accounting for changing freshwater salinity on water scarcity in global drylands.



I am also working as a project assistant for a global wetland ecohydrology network (GWEN: and I am since 2017 the national coordinator for the Swedish World Water Day (Världsvattendagen:

My main research focus is now on improve water scarcity estimations for the world’s dryland regions. This project aims to target the major scientific challenge of assessing main drivers of freshwater salinization and quantify present and future salinity-driven water scarcity in global drylands. This is needed because elevated salinity of freshwater resources is a common water quality issue, which could strongly affect water scarcity. Because no studies have accounted for salinity impacts on water scarcity in critical global drylands, current water scarcity estimations risk being severely underestimated. This study will achieve the aim by; 1) conducting the first coherent assessment of present freshwater salinity in global drylands; 2) combining water- and mass balance approaches to develop projections of future changes in water quantity and salinity, accounting for impacts of agricultural development and climate change, and; 3) estimate where and to what extent salinitydriven water scarcity will occur during the 21st century, through novel development of a data-driven modelling framework, considering salinity thresholds for different human water uses and ecosystems. Improved capacity to predict and prevent future water scarcity is essential for sustainable provisioning of water to end-users and the ecosystem. 

Another research focus is on landscape scale spreading and fate of substances in aqueous systems, especially regarding metal transport through coupled river-groundwater-wetland systems. I am also working on both qualitative and quantitative assessments of the large-scale functions of wetlands and the impacts of regional-global change on their functions and associated provisioning of ecosystem services.
