My research is based on a fundamental understanding of ecosystem processes, aboveground and belowground communities, and their interactions particularly in grassland and forest ecosystems. Understanding these interactions are essential to better assess and predict how global change drivers affect ecosystem functions and services such as nutrient cycling and net primary productivity.
To accomplish this, I combine several disciplines, including ecosystem ecology, community ecology, ecological stoichiometry and global change biology. Working at the interface of different disciplines allow me to get a better understanding on how organisms and ecosystems respond to global change drivers such as anthropogenic nitrogen deposition, biodiversity loss and biological invaders. Finally, I aim to use this new knowledge about terrestrial ecosystem functioning and global change to inform the large public and decision makers.
