From my background I am ecologist with main emphasis on aquatic ecosystems. During my studies in biological science I worked mainly on the analyses of aquatic systems dynamics and apply statistics to determine the main environmental determine factors shaping the community.
My main interests are general ecological questions on importance of biodiversity, structure and functional group composition of communities and their adaptation and regulation with regard to natural and environmental fluctuations. Furthermore how biodiversity, community structure, and grade of functional group complexity influences the resilience and resistance of systems.
I am interested in using microbial systems as tools to test evolutionary theories and macro-ecological concepts. Many established and recently evolved hypotheses in (macro-)ecology are often difficult to verify since they imply infeasible sampling effort, large spatial field experiment setups or are only accomplishable over long temporal scales.
Microbial systems offer the opportunity to study ecological population dynamics from the perspective of individual behaviour. Their short generation turnover and the relatively ease of system manipulation enables even complex experimental setups in small lab systems.
Direct manipulation/reduction of biodiversity/functional groups of natural microbiological communities can be used to examine how biodiversity loss affects the functionality and resistance to external disturbances.
For the future I also would like to extend integrated experimental work on microbial communities to answer theoretical ecological issues that are still little understood. Experimental and theoretical approaches on microbial ranges may help to understand complex responses of ecological communities in general and give insights on reactions of communities to a changing environment both on long and short term temporal scales.
