Short presentation

I view myself as a researcher at the interface of Limnology and Evolutionary Biology and I am especially interested on how natural selection acts upon variation and how individuals are shaped by a specific environment. Overall, my research aims to understand how ecological and evolutionary dynamics affect food webs and whole ecosystems.

My courses


During my PhD work at Leibniz-Institute of Freshwater Ecology and Inland Fisheries Berlin (IGB), I focused on the effects of structural complexity provided by macrophytes on ecological and evolutionary processes on shallow lake ecosystems. For my PostDoc in the group of Aquatic Communities and Populations of the Limnology Department at Uppsala University, I want to develop a deeper understanding on how adaptive foraging traits in organisms can change along environmental gradients in ecosystems. Our current knowledge about anthropogenic or climatic influences on the evolution of organisms is limited and there is a strong need to develop a basic understanding of environmental effects on evolutionary processes. I particularly aim to resolve the question of how increasing concentrations of dissolved organic carbon (DOC) can affect population divergence in freshwater fish through changes in energy transfer efficiency and food quality.


KAWater: Inland Water Ecosystems in the Global Carbon Cycle - towards a mechanistic understanding

Recognizing the importance of land-derived organic matter for both aquatic ecosystems and the global carbon cycle are among the prominent advances in aquatic science in recent decades. KAWater is an interdisciplinary project that will bridge disciplines including molecular microbiology, organic analytical chemistry, and food web ecology to enable a mechanistic understanding of the carbon cycle in freshwater systems, all the way from molecules to the ecosystem scale. We have set-up a mesocosm facility in Central Sweden that allows the realism of natural ecosystems, and at the same time the possibilities of controlled and replicated experimental design needed for hypothesis testing.
