Research Interests

My research focuses on understanding the role of Earth surface processes (e.g., erosion, sediment transport) in the global carbon cycle. Both natural erosion and human-driven land use change destabilize soils and transfer carbon from one reservoir to another. My goal is to link these physical processes with their biogeochemical consequences and quantify their impact on the carbon cycle.
