My research focuses on how water has shaped the landscape in the past and how current climate change and human activity affect the hydrological systems. This includes examining where and how water flows through the landscape, which in turn affects water quality. My studies primarily focus on glacial and karst landscapes, and within the displines of speleology (i.e., cave research), hydrogeology, and geomorphology. 

I'm teaching 

GEO111 - Landformdannande Prosessar (Geomorphology) (course responsible)

GEO212 - Terrestrial climate and environmental changes

GEO317 - Special topics in geography

GEO318 - Hydrology, groundwater and water-related geohazards (course responsible)

I'm supervising master's students in topics related to my research interests.
