Research Interest

As an ecophysiologist, my research interest lies in understanding the biological mechanisms behind observed patterns and processes in plants and ecosystems. In general, I aim to combine field observations with in situ and ex situ experiments to gain a better functional knowledge of plant and ecosystem processes in changing climates. My main research focus is on tree carbon relations and the limitation of tree growth under climatic stress like cold temperature or drought. 

Main research topics:

- Carbon Reserve Physiology
- Cold and Drought Stress Physiology
- Alpine Treelines
- Tree Mast Reproduction
- Plant Cell Wall Functions
