Research focus

 

In my research I am interested in how plant metabolites are shaping plant-herbivore interaction but as well the interactions in plant communities. In my current project I am studying belowground interactions that are mediated by root exudates and root volatiles. The aim is to establish a platform that will allow us to untangle the sophisticated interactions in the soil with state of the art analytical instrumentation (LC-qToF, GC-QqQ, LC-QqQ). Starting with plants of Brassica and Solanum as model systems I would like to identify major chemical markers by means of a metabolomics/ chemometrics approach. Deciphering the role of belowground plant metabolites will help to gain a better understanding how plant biodiversity is emerging and how it is maintained.
