PhD, Seniorforsker

Synopsis
My research career and research interests are concentrated on insect-plant interactions with special focus on non-target effects and risk assessment for pesticides and other toxic compounds as well as genetically modified plants. This includes both effects on plants, insects and the interaction between them. I have been involved in test methodology work and test guideline under both OECD and ISO.

Education:
May 1990, MSc. degree in biology from University of Aarhus entitled “Flight behaviour of the cabbage pod weevil and the cabbage stem weevil”. 
October 1994, Ph.D. thesis accepted at the University of Aarhus, 1994. The thesis was entitled “The impact of pesticides on interactions between weeds and insects”.
