• 2015-2017: Student assistant (research group for Biogeochemistry, Institute for Earth Sciences, Heidelberg University)
• 2012-2015: Bachelor study in geosciences (Institute of Earth Sciences, Heidelberg University); bachelor  thesis: “Isotopic composition (δD) of chloromethane in hydrothermal systems in the Taunus”

Research focus

• Nitrous oxide concentration and stable isotope measurements for identifying N₂O sources such as plants, phytoplankton and quantifying N₂O fluxes from lakes, permafrost soil and glaciers using cavity ring-down spectroscopy
• Methane cycle in lakes with specific consideration of CH₄ accumulation in the oxic water column based on concentration and flux measurements as well as the stable carbon and hydrogen isotope composition of CH₄
• Methane production and its underlying mechanisms in plants and fungi using concentration measurements and stable isotope techniques

Analytical Experience

• GC-FID
• GC-BID
• GC-MS (including pre-concentration units)
• GC-IRMS (including pre-concentration units)
• Cavity Ring-Down Spectroscopy (Picarro G2201-i and Picarro G5131-i for the measurement of CH₄ and N₂O concentrations and their stable isotope values) in field and laboratory application

Fellowships

• 04/19-03/20: Zukunftskolleg Fellow at the Heidelberg Center for the Environment (HCE)
