Research Interests

My studies aim to unravel spatiotemporal redox dynamics in soils along with the associated biogeochemical processes by incorporating methods that come from the soil chemical and physical field. Thereby, soil sampling and characterization is a major part of my routine that sometimes includes (long-term) environmental monitoring data to predict how soil genesis will proceed under progressing climate change. Specifically, I further developed the application of Indicator of Reduction In Soils (IRIS) tools by using manganese oxides as redox sensitive minerals, to document reducing conditions in soils.
