Alexandre de Saint Germain obtained his PhD thesis in 2012 at IJPB-INRAE (France) in the group of C Rameau, where he studied Strigolactone signalling. After a first post doc at the SALK Institute (La Jolla, USA) working on the Strigolactone receptor family (2013-2016) and a second Post doc at IJPB (2016-2020) on allelochemicals perception, he obtained, in 2020, a permanent position at INRAE. He is now developing a new thematic on allelopathy in the Strigolactone and Allelochemical Signalling (SAS) Team at IJPB. His current research aims to decipher the genetic and molecular mechanisms of chemical belowground plant-plant interactions.
