We investigate how atmospheric CO₂ levels and global climate are regulated by natural feedbacks on geological time scales. For that, we analyse modern and past carbon cycles with various geochemical methods.

We use cosmogenic nuclide and stable metal isotope methods to quantify rates and processes involved in cycling of elements and sediment over time. Broadly speaking, we quantify global matter cycling through Earth's reservoirs to understand Earth's evolution.

We study how different landscapes react to changes in climate, biota or tectonic events. To this end, we determine the speed of erosion and weathering processes and reconstruct the temporal sequence of landscape changes.

Cosmogenic nuclides are a state-of-the-art tool to quantify rates of Earth surface change (weathering, erosion) and can be employed to constrain the age of landforms, such as moraines or terraces.

We are dedicated to developing innovative analytical techniques for measuring stable metal(loid) isotopes. By utilizing novel stable metal isotopes, we investigate the processes of weathering and erosion on Earth's Surface from local to global scales, contributing to our understanding of global sediment cycles, past climates, landscape evolution, and geological processes.
