Biography

I was raised and schooled in Lund, and so my undergraduate studies in biology were accomplished at Lund University. I did my bachelor thesis on the impact of a pesticide (a neonicotinoid) on solitary bees, and since then I have been very fascinated by bees and pollination ecology. That, together with birding, botany and other nerdy interests, brings me out in nature whenever I have an opportunity. I am also interested in painting, literature and climbing.

Research

Bumblebees, an important group of pollinators, are in decline. Furthermore, the species composition of bumblebees has changed dramatically over time. Several reasons for these declines and community changes have been suggested, of which the most important one may be land-use change, including habitat loss and fragmentation. But what exactly is it in the changing landscapes that negatively impacts bumblebees, and why are different species seemingly differently affected?

In my PhD project I am aiming to understand the mechanisms that determine how bumblebees utilize resources in the landscape and how this impacts their fitness. I will look at the effect of flower resource variation in time and space, investigate diet, colony growth, reproduction and morphology and also add an historical aspect by investigating museum specimens. I hope my research will bring new light to the reasons behind pollinator declines and provide a foundation for more efficient conservation measures.
