Research Interests
I am working on a series of climate chamber experiments with the aim to improve our understanding of the role of BVOCs in plant-plant and plant-soil interactions. Further, I am interested in the effect of environmental stress on BVOC emissions and metabolic pathways in plants and soil. Our experimental set-up with an automated flow-through gas measurement system allows us to analyze the real-time gas exchange of plants including VOC emissions and isotopic signatures.
Ecosystem physiology, soil ecology, soil-plant-atmosphere interactions, plant-microbe interactions, nutrient cycles, volatile organic compounds, soil respiration, PTR-TOF-MS, stable isotope ecology.
