Research interests
I study the biology of insects, especially ants, bees, social and parasitoid wasps (collectively known as Hymenoptera)
My main interests are insect diversity across different landscapes, invasive species, and taxonomy.
Currently I am interested in compiling and using big datasets to answer environmental questions, and particularly using historical information from natural history collections, such as insect decline, and spatial and temporal patterns of biodiversity.
