I am a forest ecologist and entomologist specialising in the ecology, impacts and management of non-native and native forest insects and other taxa. I am also passionate about the biodiversity of insects, birds, and vascular plants, and relationships between biodiversity and ecosystem functioning. In recent years, much of my research has focussed on bark beetles and other wood and bark-boring insects, groups that include many of the highest-impact invaders of forests world-wide. Another key research interest is the role of forest biodiversity in the biotic resistance to insect pests and invasive species as well as other ecosystem services. Finally, I am also studying effects of land cover and land use change on insects, birds and plants.
I enjoy networking and collaborate with colleagues in many countries across the world. For example, I am working with colleagues in New Zealand’s Better Border Biosecurity (B3) Collaboration and in the international EU-funded project “HOMED”, and I participated in several collaborative projects at the National Center for Ecological Analysis and Synthesis (NCEAS, University of California) and the National Socio-Environmental Synthesis Center (SESYNC, University of Maryland) where I studied relationships between propagule pressure (i.e., arrival rates of non-native insects) and successful establishments.
In my lab at WSL, several postdocs, students, and I are working on projects on a range of topics including: a national surveillance programme for invasive forest insects with a focus on trees in urban environments (Benno Augustinus), insect invasions in terrestrial and freshwater habitats (Agnieszka Sendek), effects of bark beetle outbreaks and deadwood on woodpecker populations (Marco Basile), fungal associates of ambrosia beetles and bark beetles (José Correia), effects of drought on saproxylic insect assemblages (Timothy Work), and population genetics of bark beetles (Julia Kappeler and former MSc student Lea Bischofberger).
