I specialize in utilizing remote sensing techniques, such as Sentinel-2 optical and Sentinel-1 SAR imagery, combined with seismological and environmental data to study landslides in Norway. 
My work also involves the usage of deep learning algorithms to automate landslide detection and assess triggering mechanisms through spatial-temporal correlations with seismic activity and precipitation.

I have presented my work at multiple international and national conferences, actively contributing to scientific discussions on landslide detection and analysis. The abstracts can be found in the following publications: ESC 2024 Abstract Book (pg. 493) and Geofaredagen 2024 Abstract Book (pg. 21). I have also presented my PhD research topic at Forsker Grand Prix 2025 in Bergen.
