About me

I am a researcher in water and climate at the Department of Earth Sciences, Uppsala University and a project coordinator at the Centre of Natural Hazards and Disaster Science (CNDS).  With a background in physical geography I want to understand processes and interactions in human-environment systems.


My research work focuses on surface water hydrology, with emphasis on interactions between water-human-ecosystem responses to environmental change, and covers a number of areas, including (i) hydrological extremes, focusing on interactions between floods and societies, and (ii) hydrological changes in relation to disturbance regimes (e.g., wildfire). The central approach of my research is to use the increasing availability of open Earth observation data and worldwide archives to explore spatial-temporal patterns in hydrological changes and human-environment interactions. My research focus is process oriented, and I use a systems approach to understand concurrent changes.

In HydroSocialExtremes, I use Earth observation data, e.g., nighttime lights satellite data as a proxy for human settlements, to explore how the occurrence of major floods relates to changes in settlement dynamics in floodplains.
