I am a plant community ecologist interested in temporal and spatial patterns of biodiversity and ecosystem functioning in forest and grassland ecosystems. I am particularly fascinated by the role of biodiversity in driving the capacity of ecosystems to resist and recover from global change drivers, such as land-use change, biological invasions, and fertilization. I examine these topics using experimental and observational studies and synthesis.
How do biodiversity and biodiversity-dependent ecosystem functions vary across scales ?
How does biodiversity enhance or buffer ecosystem responses to global change drivers?
To what extent do global change drivers affect mechanisms underlying biodiversity ?
