I work with experimental plant physiology, and do experiments in the field and under controlled environment conditions in the Phytotron. Previously, I have worked with the abiotic stress of tropsopheric ozone on several herbaceous species, partly using biophysical methods. I studied the effects of long daylength (like during summer in Nordic countries) on development of ozone-induced injuries. The causal link between the light signalling molecule phytochrome and the observed daylength dependent response was established.

Since 2012 I have worked with an insecticide free protection method for spruce seedlings (Picea abies) against pine weevils (Hylobius abietis), feeding on the bark. Melted wax is applied on the lower shoot parts of seedlings before they are planted in the forest.When the wax is cooled, it forms a physical barrier protecting the bark.The method is an environmentally friendly alternative to insecticide treatments, normally used all over Europe during reforestation. In 2015, a field experiment (Alvogran) was established in a coastal forest in Vestfold, in an area with high abundance of pine weevils. The protective properties of an insecticide (the neonicotinoid amidacloprid) and wax are compared over a period of two summer seasons. It is normally assumed that the young spruce plants need protection for two years after a clear-felling. These are the years with the highest abundance of pine weevils and at the same time the most important period for the young plants, when it comes to getting established in their new environment.

In 2016, a new project (BiVaGran) to improve the wax protection method was started. In this project, I will study the spruce seedlings' tolerance to heat and physiological and genetic responses to heat stress. Further, I will do experiments with waxed seedlings and pine weevils to learn more about their behavioral reponses to additives in the wax. These experiments will be done in cooperation with Swansea University, UK.

During 2012-2015 I worked for the WeevilSTOP project (supported by the EC 7th framework programme). I have been studying the responses of young Norway spruce plants to a range of methods of wax application. The wax is hot when it is applied, so the effects of heat have been among the subjects I have studied. Root growth is important for the establishment of young spruce plants in the field. Therefore, root development have been given extra attention, for instance via an X-ray micro-computerized tomography (CT) method of studying undisturbed roots inside a soil core. This study was performed at the University of Nottingham, UK.
