Since 10/2018 Research associate at Institute of Geology and Paleontology, University of Münster 2016-2018 Postdoctoral researcher at the GEOMAR Helmholtz Centre for Ocean Research, Kiel (SFB754) 01/2016-07/2016 Fulbright research fellow at the Department of Geological and Atmospheric Sciences, Iowa State University, Ames, USA 2011-2016 Dr. rer. nat., University of Tübingen, Germany 2005-2011 Diploma in Mineralogy, University of Tübingen, Germany Research
I am broadly interested in the stable isotope geochemistry of bio-relevant elements (e.g. carbon, sulfur, nitrogen, oxygen and phosphorus) and trace metals (e.g. molybdenum and iron) as well as their biogeochemical behavior and cycling in sedimentary and aqueous (paleo-)environments. Understanding these processes and associated formation/reaction of mineral phases are paramount for their development and application as environmental proxies. In turn, this allows to reconstruct past biogeochemical conditions and processes from the geological record. In this context, I am investigating biogeochemical processes in modern marine and lacustrine (sedimentary) environments where the target elements are involved with to approach the following issues:
• Formation and preservation of geochemical signatures in the sedimentary/geological record
• Trace metal cycling in sediments during early diagenesis
• Role of sulfurized organic matter in particle-driven nutrient and trace metal cycling in the sediment-water interface
• Trace metal incorporation in authigenic and detrital particles (e.g. carbonate, clay, oxides, sulfides)
• Investigation of carbonates and stromatolites as paleo-environmental archivesGrants and other activities
• Fulbright Fellowship for a research stay from January to July 2016 at the Iowa State University in Ames (USA) (8,000 €)
• Reviewer for Geochimica et Cosmochimica Acta, Earth and Planetary Science Letters, Radiation Physics and Chemistry, Marine and Petroleum Geology
• Postdoc representative (Research Division 1) within the GEOMAR Woman’s Executive Board (WEB)Publikationen
