I  contribute to the teaching on courses in Ecology, Plant protection and Insect Chemical Ecology



My research is focused on studies on plant-insect interaction. The main topic is sensory physiological and behavioural mechanisms involved in host plant choice of herbivorous insects. In these studies my focus is on the detection and neural integration of olfactory plant cues and how they affect behavioural decisions. My studies also investigate how insects deal with a varying environment through phenotypic plasticity. How does it change host plant preference and what is the role of intra- and trans-generational experience?  Furthermore, I explore the ecological consequences of phenotypic plasticity and the costs and benefits involved during host plant choice.

I am also involved in studies:
* monitoring and sustainable control of oilseed rape pests both in single crop and intercropping system

* effcets of increased atmospheric CO2-levels on insect host plant performance and preference
