Since 2018, I have lectured various courses on soil science and hydrogeography, as well as field and laboratory practicals at the Department of Geography, Philipps University.
At the IAG, my current focus includes lectures and courses on basic soil science, soil protection and pollutants in soils, as well as applied field soil science and support for laboratory practicals.
