| Research profile | |
| Main research interest is the functional interaction between the plant and its microbiome. Native bacterial diversity and selected bacterial strains significantly impact plant nutrition and plant vitality. Functional interactions are analysed by complex omics techniques, from the plant and bacterial point of view, depending on the plant genetic composition and N- and P-fertilisation strategies. Additionally, the risk and pros of diverse bacterial community compositions are my focus of interest in respect of potential human pathogenic bacteria and probiotic acting bacteria. Advisory work is conducted for farmers applying bacterial preparations, and for politics in biodiversity. She has been involved in collaboration work and leading scientific projects with more than 12 countries on 4 continents. Her research work is published in more than 50 scientific articles and she supervised 11 PhDs and examined 8 theses in 6 countries.
