Corinne Vacher (Research Director in Ecology at INRAE, France)

My research focuses on the relationships between plant microbiomes and plant health. I combine network ecology, environmental genomics, plant pathology and plant physiology to analyze microbe-microbe interactions and plant-microbe interactions, with the goal of discovering their influence on the health and function of ecosystems (temperate forests, tropical forests and agricultural systems including vineyards). Applied perpectives include biocontrol of plant diseases and  biomonitoring of ecosystem health.

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). 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 also have strong collaborations with the researchers of the SAVE research unit (INRAE, Bordeaux Sciences Agro), with whom I study the relationships between grapevine microbiome and grapevine health.

Do not hesitate to contact me if you are interested in a collaboration (corinne.vacher[a]
