Research focus

 

My current research focuses on the identification of volatile organic compounds (VOCs) released from the cereal holobiont under different environmental stresses, accessed by thermo desorption - gas chromatography coupled to mass spectrometry (TD-GC-MS). I am involved in the VolCorn project, which aims to deal with the effects of climate change in wheat. Climate changes include an increased frequency of weather extremes which eventually result in plant abiotic stress factors like drought and flooding, which can have an impact on global crop production. We use an interdisciplinary approach involving combined expertise of four different institutions of the Leibniz association (iDiv, IGZ, IPK, ZALF) to investigate interactions between wheat and its associated microbiota, especially arbuscular mycorrhizal fungi (AMF), under the influence of induced drought and flooding events focusing around the emission of volatile organic compounds (VOCs) emitted by the plant and the microbiota.

Due to my background in analytical chemistry and design of experiments, I also support method development and optimization for LC-QqQ-MS, LC-qTOF-MS and GC-QqQ-MS to investigate the multitrophic interactions associated with plants on a chemical level. Besides that I am investigating primary and secondary metabolites and degradation products contributing to ongoing research in the working group and multiple cooperation partners.
