Central focus points of all my research activities are the interactions between abiotic stresses, genotypes and climatic conditions. For stress perception and communication, root shoot signals and their modification by climatic factors are of particular interest to me.
Ion uptake and distribution if dependent on transpiration determine the genotypic tolerance levels in environments with varying levels of air humidity in saline and iron toxic conditions.
Roots may benefit from specifically targeted carbohydrate allocation in a drought stress situation in order to provide better access to water.
Crop phenology as dependent of temperature determines the suitability and the flexibility of genotypes within changing cropping systems.

Below you will find a selection of research highlights from recent years summarized by topic in a few, hopefully informative slides
