My research addresses the impacts of seasonality and disturbance on biogeochemical processes. I ask questions at the ecosystem scale, with emphasis in two directions: (1) ecosystem biogeochemical response to global change, such as the feedbacks between climate change, carbon (C), nitrogen (N) and phosphorus (P) cycles and vegetation communities, and (2) microbial community structure and function, with the purpose of understanding the relationship between soil microbial community and ecosystem processes.

Many of my research questions investigate temporal variability, to understand how biotic and abiotic seasonality interacts with disturbance or climate drivers. I use a combination of field sampling and field and laboratory experimental manipulation, followed by biogeochemical and molecular analysis and post-hoc statistical modeling. The majority of my research has been in arctic landscapes, but my questions are broadly applicable to any ecosystem, and I have applied my research in high and low arctic tundra, boreal forest, temperate grasslands and Mediterranean ecosystems.
