The focus of my research program is to develop sound methods and procedures for risk assessment of genetically modified (GM) plants with the focus on the establishment of laboratory tests for assessing the potential effects of GM plants such as insect-resistant GM corn, rice and cotton on different non-target arthropod species. Meanwhile, I am also working on the plant and insect chemical ecology to understand the interactions of plant, pests and natural enemies and the plant-mediated interactions in herbivorous insects.
