Corinne Vacher (Research Director in Ecology at INRAE)

My research focuses on the role of plant microbiomes in the functioning of terrestrial ecosystems. I combine ecological network inference, environmental genomics, plant physiology and pathology to uncover microbial interactions and understand their influence on the health and function of ecosystems (temperate forests, tropical forests and vineyards). Applied perpectives include disease biocontrol and ecosystem biomonitoring.

I am part of the BIODIV team (Diversity of biotic interactions and functioning of forest ecosystems) within the BIOGECO research unit (INRAE, University of Bordeaux). I run the Phyllolab (Phyllosphere Ecology Lab). I received my PhD in Evolutionary Biology in 2004 (University of Montpellier, France) and my accreditation to supervise research in Ecology (HDR) in 2014 (University of Bordeaux, France). Do not hesitate to contact me if you are interested in collaborating (corinne.vacher[a]
