My research activities focus on past, present, and future glacier, climate, and environmental changes in the high mountains. The regional focus is currently on the Alps, the Karakoram, and the Ethiopian Highlands. To document and analyse the evolution of mountain glaciers and to better understand the underlying processes, various methods are applied:
- Mapping and surface exposure dating of glacial geomorphological landforms to reconstruct glacier fluctuations during the last glacial period (e.g. on the Swiss Plateau and in the Ethiopian Highlands)
- Mass balance studies on the Kanderfirn in the Swiss Alps since 2017 and on the Passu Glacier and Ghulkin Glacier in the Karakoram since 2021 to monitor recent changes
- Development and application of autonomous drones for aerial surveys of glacier surfaces and for atmospheric sounding of the boundary layer above
- Use and further development of numerical models to simulate the mass balance and evolution of glaciers
