Interest, Vision and Field Work
My research interests concern mountain environments and climate change, especially
- steep alpine permafrost
- cryosphere control on slope movement and stability in heterogeneous alpine cryosphere
- process understanding and quantification of phenomena in mountain permafrost with sensor instrumentation, measurements and models.
The vision for my research is to understand, to quantify and to model processes in mountain permafrost (e.g. frost weathering at different depth) combining lab experiments and field measurements in high mountain environments (e.g. acoustic emission, temperature and capacitance for moisture). For this, the combination of geo-science and engineering is very useful and enables field measurements at locations in difficult to access environments.
I greatly enjoy doing field work in alpine environments and being able to combine my knowledge as well as my experience with my alpine skills.
