I study how changing environmental and tectonic conditions impact topographic adjustment of fluvial landscapes and their sedimentary products. In particular, I try to understand how river-valley geometry relates to climatic and tectonic boundary conditions and how information on those condititions are translated into sedimentary signals, which get potentially modified during sediment transport. I study this by combining field and laboratory methods with remote-sensing analyses.
