Dario Gioia works in the fields of tectonic geomorphology, geomorphological hazard geoarchaeology, landslide mapping and monitoring, the morphometry of drainage networks, and the stratigraphical and structural evolution of tectonic basins. His research also focuses on topics of quantitative and theoretical geomorphology, such as the application of the landscape evolution model (LEM) to investigate the recent evolution of fluvial and coastal environments and the development of geomorphic indexes to solve issues of landscape/landform classification. His research methodological approaches include geomorphological and geological surveillance and photo-aerial interpretation, DEM-supported morphometric studies of landscape and river network evolution, and satellite and field-based monitoring of landslide activity.
