I am a researcher in the Integrative Ecology Research Group of the Eötvös Loránd Research Network (ELKH), hosted by the Eötvös Loránd University (ELTE) and the Hungarian Natural History Museum (MTM), Budapest, Hungary. I am particularly interested in ecology of ground beetles (Coleoptera: Carabidae). I've been working on radio telemetry, habitat use and movement patterns of selected large species as well as community ecology of carabids in managed temperate forests, agricultural landscapes and post-mining areas in Central Europe.

Currently, I explore how the different management practices of two silvicultural systems, represented by rotation forestry (clear-cuts, preparation cuts, retention tree group) and continuous cover forestry (gap-cutting), can affect ground beetles at different levels of the organization, from assemblages and species populations to individuals and their behavior.

Do you have a garden? Please, participate in our Home gardening project. We investigate what plant protection habits are typical among garden owners and what factors influence their gardening practices in ten countries from Central, Eastern, and Northern Europe. Our goals are to expand our current knowledge on the motivation for gardening and the gardening practices of garden owners, as well as to obtain information about the insect diversity of home gardens.
