During my PhD, I studied how plant-insect interactions respond to changes in temperature. More specifically, I focused on how timing of bud burst and leaf senescence of the common oak Quercus robur influenced insects herbivores associated with Q. robur. I found that temperature-induced changes in both bud burst and leaf senescence had an impact on the herbivore community. For one outbreaking herbivore, the leaf-mining moth Acrocerops brongniardellus, timing of bud burst had a large impact on infestation levels – where oaks with an early bud burst escaped infestation while later oaks did not.
In my current position as a postdoc, I examine how uneven-aged silviculture influence biodiversity, forest growth and tree regeneration. I intend to identify potential synergies or trade offs between the two management strategies (even-aged and uneven-aged silviculture). The project is a part of the strategic research collaboration with Stora Enso.
I graduated from the master program in Biology at Uppsala University in 2014. After that I worked in the field for the The Swedish National Forest Inventory. In 2016, I started a PhD in insect ecology at the Swedish University of Agricultural Sciences in Uppsala. I finished my PhD in July 2020 and started to work as a postdoc in the same year at the Swedish University of Agricultural Sciences in Umeå.
