Research
In my research, I explored how atmospheric and climate change could impact natural ecosystems, with a focus on mountain environments. I linked plant physiological and growth measurements with biogeochemical, hydrological and climate data with the aim to predict changes in biodiversity and ecosystem functioning and services.
