2016 - 2017, ETH Zurich, Dept. of Environmental Systems Science

Martin Ackermann's group uses experimental evolution with bacteria to investigate fundamental questions about evolutionary biology. The main focus is on phenotypic variation - phenotypic differences between individuals with or without underlying genetic differences. The group investigates how selection acts on the mechanisms that control the level of phenotypic variation, and how the level of phenotypic variation can influence the course of evolution. A second area of research is the evolutionary origin of aging. Experiments with bacteria are used together with theoretical models to investigate when and why aging originated in the history of life. more

Prof. Andreas Kappler

University of Tübingen, Center for Applied Earth Sciences

Andreas Kappler's group focuses on the interactions of microorganisms and iron-minerals in modern and ancient environments. These interactions also largely determine the fate of harmful organic and inorganic pollutants. Microbial iron-oxidizing and -reducing communities play a key role in iron-mineral formation and transformations. Studying both biological molecular mechanisms and geochemical conditions are crucial to the understanding of these biogeochemical processes. Therefore, we combine microscopic, spectroscopic and molecular techniques with geochemical analysis in order to understand modern and ancient iron biogeochemistry and its environmental impact. more
