Research Profile
Main research areas are plant – pathogen interactions with a particular emphasis on soil-borne pathogens such as Rhizoctonia solani and Verticillium spp.. Soil-borne pathogens are difficult to control and disease incidence and severity are affected by abiotic and biotic factors. The main goal of her research group is to determine how cultivation conditions affect the incidence and severity of soil-borne diseases (performance of monitoring) and how severity can be reduced by management practices. The group studies the impact of pathogens on plant responses at molecular and metabolomic level. RNA-seq analysis supports the improved understanding of plant and pathogen responses during the interaction process. Several third-party funded projects have contributed to a better understanding of the development of biological control methods against diseases caused by soil-borne pathogens. Biocontrol agents to enhance plant health were studied at field scale considering the rhizosphere competence of such inoculants. Recently, the impact of long-term farming practice on soil and rhizosphere microbiome is studied within the frame of a third-party project.
