Research Summary

Earth and planetary geomorphology; watersheds, rivers, and floodplains; basin analysis; fluvial biogeochemistry.

Courses & Teaching

Geomorphology (EESC / GEOG 222); Stratigraphy and Sedimentology (EESC / GEOG 356).


I was born in Italy and have been drawn to rivers and mountains since I was a child. The passion for landscapes is what eventually led me to geology, and specifically the study of surface processes. I found my perfect geoscience playground in Arctic Canada and the deserts of the western USA. I love meandering rivers, remote fieldwork, old-growth forests, and wolf biology.
