AboutMediterranean, sometime Classical, archaeologist. Currently I am researching the relationship between the ancient Romans, their volcanic landscape, and their built environment as director of the “Quarry provenience and Archaeological Dating of the Roman-Area Tuffs in Antiquity” (QUADRATA) Project. I also continue to study cult places in the context of local and regional political developments, with a particular interest in the 1st millennium BCE central Mediterranean, and am working on the architectural and ritual development of the sanctuary of Fortuna and Mater Matuta in Rome’s Forum Boarium during the Middle Republic, based on my recently completed dissertation titled “The Roman Middle Republic at Sant’Omobono.”
