Research interests
I am a quantitative ecologist working at individual, population, community and ecosystem levels, with a strong focus on arctic ecosystems, both terrestrial and marine. My interests are in developing better designs, analytical methods and models for different systems, in particular in the context of long-term monitoring of ecosystems, so as to answer questions related to attribution and mitigation of climate change impacts. This has led to recent works developing short-term forecasting methods and models closely linked to management.
