Function and Responsibilities:

I am a PhD student working with Dr. Niels Hovius and Dr. Dirk Sachse to study the influence of fluvial geomorphology on the transport of organic carbon from source to sink. My research is funded through the DFG-supported StRATEgY international research training group.

Research Interests:

- Role of rivers in the carbon cycle
- Biomarker transport and preservation
- Landscape evolution in active foreland basins

Geomorphic controls on terrestrial organic carbon transport and preservation in alluvial river systems
Our natural laboratory is the Rio Bermejo in northern Argentina, which is one of the only rivers draining the central Andes and crossing the Andean foreland to reach the Rio Parana. We analyze the organic carbon in both suspended and floodplain sediment, using methods in sedimentology ( sed lab), organic geochemistry ( OSGL lab), and cosmogenic nuclide geochemistry ( HELGES lab).
