My primary research interests include landscape evolution and tectonic geomorphology, and more recently I became interested in the role that rivers play in the organic carbon cycle.
Rivers are sensitive recorders of landscape change, and can serve as a profound signal for active tectonic, climatic, biotic, and anthropogenic processes.
My natural laboratory is the Rio Bermejo in northern Argentina, which transports a significant volume of sediment and terrestrial organic carbon from the mountain range to the Paraguay River, which eventually reaches the Atlantic Ocean. The primary research questions I aim to solve include:
- Is dynamic topography influencing the planform geometry and flow regime of river systems draining the eastern flank of the Andes?
- How do leaf wax biomarkers evolve as they are transported downstream in a river system?
- Where and over what timescales does microbial degradation of organic material occur in a river system?
