Brief description of the main scopes: 

Community assembly in grassland ecosystems: We study how local and landscape-scale effects govern community assembly and how we can improve ecosystem services and local conservation measures.

Previous topics:
Topology and dynamics of biological networks: In the Centre for Ecological Research, We investigated how well simple analyses can identify key species and important direct and indirect interactions.
Ecology and evolution of avian lice: In collaboration with the University of Veterinary Medicine Budapest, we investigated the ecology and evolution of bird lice. We focused on vertical transmission and the evolution of louse body size and sexual size dimorphism.
Conservation biology and ecology of Red-footed Falcons: In collaboration with BirdLife Hungary, we investigated a wide range of topics concerning the ecology and conservation of Red-footed Falcons (Falco vespertinus).

Main profile in keywords: 
Community ecology, parasitology, network biology, ecosystem services, conservation
