Introduction
Geomorphologist, teacher and researcher. Her main topics of interest are geomorphological mapping applied mainly to coastal environments, and the relationship between human settlement and natural environments. She has developed the use of geomorphological and geoarchaeological indicators in the study of coastal evolution and sea level change. Rock coasts are her preferred research environment, where she investigates also those processes that are currently shaping the shoreline

The aim of this work is testing a cheap and user-friendly methodology suitable for studying temperature fluctuations of coastal rocks’ surfaces. An infrared thermometer was used, that permits a contactless measurement of the average surface temperature of a patch around a measuring point. Temperature was measured in an array of selected plots every...
Article
There are areas in the world where our understanding of past sea-level changes is less robust than in others. This is partly due to the difficulty past investigators had adopting i) high-resolution elevation measurement techniques (largely available only in the last decade) and ii) standardized methodological approaches to reconstruct past relative...
Article
Bioerosion and bioprotection (bio-remodeling) is the action exerted by biota colonizing rocky shores. It represents an important component among processes responsible for shaping coastal landforms, and a clear evidence of interaction between the biosphere and the solid earth. Barnacles extensively colonize the midlittoral belt of rocky shores in th...

Rock coasts and shore platforms are conspicuous landforms along the Mediterranean and Black Sea (MBS) coasts. These coasts have been fashioned by changes in sea level because of vertical movements of the land and variations in eustatic and isostatic sea-level. For this reason, the Quaternary evolution of MBS coasts has been extensively studied, eve...
