I study the ecology of insects and plants in agricultural landscapes. I explore how land use, landscape structure, and biodiversity conservation affect the distribution, abundance dynamics and functions of biodiversity, with focus on organisms that provide the ecosystem services biological control of agricultural pest insects, and crop and wild flower pollination by insects (bumble bees, solitary bees, hover flies and butterflies). I participate in interdisciplinary collaborations that aim to translate the attained ecological information into support for policies and development of land management that support biodiversity, ecosystem services and agricultural production.

Research team and resources
