Research interests

My research uses experimental and field approaches in plant ecology, plant physiology and pathogen evolution to answer fundamental questions regarding the impacts of the environment on biotic interactions and trait evolution in the context of global changes. More specifically, I’m currently doing research on the impact of abiotic and biotic factors on grapevine physiology to understand the underlying mechanisms of grapevine dieback.
