Research interests
- Symbiosis
- Plant-Ant Interactions
- Microbial Diversity in various ecosystems
- Tropical Ecology
My research mainly focuses on investigating microbial communities and their potential functions in various ecosystems. To address ecological questions, I am mostly applying molecular and stable isotope techniques. Currently, my main focus lies on bacteria, fungi and also nematodes being present in special compartments – so called patches – located in the nests of Azteca ants inside Cecropia trees. This ant-plant mutualism is widespread in the Neotropics and turned out to be a stunningly complex multi-species-network. Additionally, due to my broad research interests, I have been working on identifying N2-fixing bacteria and studying their distribution patterns in grasslands and biological soil crusts.
