My research work concerns the evolution of continental surfaces either due to tectonics or climate forcing, or a combination of the two. My toolbox includes quantitative geomorphology, and cosmogenic nuclides (either in situ or atmospheric). I used to work in active geodynamical settings, mostly along convergent plate boundaries (Argentina, Iran, Morocco, Taiwan). I now develop a research program in Brazil to study long term landscape evolution and global change impacts on continental surfaces.
