Research Intrest

I am a plant biochemist who specialises in Mass Spectrometry. My research has primarily focused on plant physiological responses to growth and environmental constraints such as drought and pathogen infections. In particular, I have used '-omics' techniques (specifically transcriptomics and metabolomics) to study the metabolic regulations underpinning redox signalling upon biotic stress. I mostly used the model plant Arabidopsis thaliana for genetic approaches. As a P3 Independent Research Fellow, I now translate my research into various crops (maize, oilseed rape, tomato, to name but a few). I am involved in many different projects (including, chemical priming, rhizosphere chemistry, impacts of (photo)respiratory pathways and climate change on defence responses, benzoxazinoids signalling) by extensively using Mass Spectrometry techniques (MALDI-, UPLC-q-TOF) to detect adjustments in plant metabolomes. My key research interests are: rhizosphere chemistry: profiling root exudates, benzoxazinoids signalling, in collaboration with Jurriaan Ton metabolic regulations of the plant immune system: priming of plant defences, hormonal balance and (photo)respiration signalling NAD signalling in response to development and stress
