My research subject is the variation in induced resistance against bark-feeding insects among different genotypes of conifer seedlings, which is aim to reveal the resistance mechanisms in conifer seedlings against bark-feeding beetles. I will work on conifer seedlings with different growing performance (possibly at different defence levels). Both lab experiments and field trials will be conducted. By examine the attacking rate together with chemical analysis, I will investigate the correlation between seedling genotypes and induced defence


I got my MSc in Beijing Forestry University. My major was forest conservation refer to pest insect control. There I conducted a comparative study of the alimentary canal morphology and cellulase in two closely related Eucryptorrhynchus species in China. The major idea is to give a better understanding of the differences in the digestive mechanism of the two species. In the middle of my master study, I spent 1 year studying 4 courses of the "EuroForester" programme about forest management in SLU Alnarp campus. These finally lead me start a PhD in Sweden about forest pest insect.
