Together with Mathieu Hanemian, we're searching for an undergrand student (Master or Erasmus internship, final-year engineering student) to explore the effect of intercropping on the soil microbiota. If this sounds interesting to you, please reach our with your CV and a motivation letter!
Internship objectives 
The main objective of the internship will be to determine how intercropping modifies the composition and 
functions of the rhizosphere microbiome associated with each cultivated species, in comparison with sole 
crops. The intern will also seek to identify common microbial signatures across different intercropping 
systems in order to highlight potential general mechanisms associated with plant diversification. Particular 
attention will be paid to the functions potentially associated with the observed changes, based on the 
identification of microbial taxa and targeted qPCR analyses. 
The intern will participate in the entire analytical workflow, from molecular biology procedures (DNA 
extraction, PCR, preparation of sequencing libraries) to bioinformatic data processing, statistical analyses 
using R, and biological interpretation of the results. The results will contribute to identifying the microbial 
mechanisms that may explain the agronomic benefits of intercropping and may help guide the development 
of new agroecological practices.
