Research interests

My research interests are focused on the impact of modern biotechnologies, especially genetically modified organisms (GMOs) on experimental model systems and on real food-webs. I am particularly interested in risk assessment and effect studies of products of modern biotechnologies. With cooperating partners, we have multiple model systems available for research: from microorganisms to Daphnia magna to insects and mammals, both in the laboratory and in the field. A particular focus has been on the food quality and ecotoxicity of GM plants (e.g. Bt-maize and Roundup Ready soy) in a feeding model using the waterflea Daphnia magna, also in combination with chemical stressors (herbicides). In the field I work with impacts of modern biotechnologies biodiversity and food-webs, both in terrestrial and aquatic systems. I also have great interest in gene flow, modeling, evolution, biodiversity, ecological interactions and invasion biology.
