Benning is a German biogeochemist studying mineral-fluid-microbe interface processes.
She is a Professor of Interface Geochemistry at the GFZ German Research Centre for Geosciences and the University of Leeds.
Her team studies various processes that shape the Earth Surface with a special focus on two aspects: the nucleation, growth and crystallisation of mineral phases from solution and the role, effects and interplay between microbes and minerals in extreme environments.
She is also interested in the characterisation of these systems, developing in situ and time resolved high resolution imaging and spectroscopic techniques to follow microbe-mineral reactions as they occur.
