Since 2005, I have been working at INRAE in Nancy on the influence of environmental factors on tree growth in the context of global changes. I have been particularly involved in the influence of climate on the dynamics of wood formation and tree-ring structure. To this end, I set up instrumented sites, developed innovative data processing methods and built an international database. More recently, I have started working on detecting treeline upward shift, attributing possible causes, and forecasting future consequences in terms of carbon sequestration, biodiversity conservation, and ecosystem services. I am very excited to stay at WSL (in the Forest Dynamics RU) from September 2020 to March 2021 to exchange and collaborate about these topics with many of you.
