PhD, 2008 University of Göttingen,
Germany I completed my MSc in biology
in Osnabrück and Berlin, working on the diversity and distribution of oribatid
mites in the canopy of a Central European mixed forest in Switzerland. After spending two years as a research
associate in the biodiversity
informatics lab (Botanic
Garden and Botanical Museum Berlin-Dahlem, Freie Universität Berlin), I returned
back to the forest in 2005 and started working towards my PhD degree in
biodiversity and ecology in the Agroecology
lab, University of Göttingen. I received a scholarship within the DFG Research Training Group 1086 “The role of
biodiversity for biogeochemical cycles and biotic interactions in temperate
deciduous forests” to investigate arthropod diversity and multitrophic
interactions across a tree diversity gradient in the Hainich National Park. My
interest for forest arthropods was first triggered as an undergraduate exchange
student at the University of Victoria, BC, in 1999/2000. In 2008, I happily
returned to Canada to familiarize myself with insects at low temperatures and
climate change, and joined the Sinclair lab as a postdoctoral fellow in the
quest to fight back the emerald ash borer (EAB, Agrilus planipennis,
Buprestidae). The
EAB is an invasive beetle species with devastating effects on Canada’s ash
populations, infested trees die within short time. Together with Jill Crosthwaite, I work on cold tolerance of the EAB.
In particular, we aim to predict temperature constraints on its potential
distribution across Canada. We installed dataloggers for measuring microclimate
in ash trees, and I will conduct experiments to investigate climate change effects.
I am especially interested in figuring out how climate change effects such as
sudden warm spells in winter, and late cold snaps in spring, affect fitness and
survival of EAB larvae and prepupae. |
