Federica Vacatello

Federica Vacatello was born in Caserta (Naples, Italy), on 11 February 1991. Actually, she is Post-PhD Researcher in Post - Classical Archaeology at the Department of Antiquity Sciences, ‘Sapienza’ University of Rome. She obtained his PhD in Post-classical Archaeology last May 2022, with a research of landscape archaeology in the alto-lazio coastal context. Currently, she is a component of the of Holy Sepulcher’s project like supervisor for the topographical documentation and the management of excavation activities.
In 2018 she graduated from the School of Specialisation in Archaeological Heritage at the University of Rome "La Sapienza" with a degree thesis on the topographical investigation surrounding the Leopoli - Cencelle site, with a grade of 70/70 cum laude. In that years she obtained a diploma and licence to drive remotely aircraft (drones), for the very light and light classes with ENAC (Italian Civil Aviation Authority) certification and authorisation. In fact, since 2016, her research interests have focused on Medieval Topography and Landscape Archaeology, with regard to methodologies’ and instrumentation's development and testing suitable for territorial surveys. In 2016 he graduated in Archaeology at the University of Rome "La Sapienza" with a thesis on the medieval funerary space of the city of Leopoli - Cencelle with vote 110/110 cum laude receiving the title of "Excellent Graduate" in Post-Classical Archaeology of the a.a. 2015/2016.
To support this activity, she won in 2016 the scholarship offered by the CISAM Foundation (Centro Italiano di Studi sull'Alto Medioevo) on the occasion of the LXIV study week (31 March - 6 April 2016) entitled "Monachesimi d'Oriente e d'Occidente" at Spoleto. Finally, in March 2016 he was awarded the diploma of Instrumentum domesticum at the Pontifical Institute of Christian Archaeology.
To aid research activities in 2018, she won two different projects like scientific manager: an Early Carrer Grant from the National Geographic Society for the development of "UAVIMALS", a small aerial scanner, and a Type I Research Initiation Project, funded by the Sapienza University entitled "A new technology for Archaeological data acquisition and topographic survey. The aerotopographic survey on the slopes of the medieval city of Leopolis Cencelle", aimed at testing a new methodology for the topographic documentation of different archaeological contexts, using drone, aerial photogrammetry and GIS software. Lastly, in 2021, it was awarded a second Type II Research Initiation Project entitled "Remote Sensing the Invisible. A new application of colorimetric and radiometric techniques for the aerial survey of the archaeological presence inside and outside the site", aimed at engineering an aerial camera useful for the colorimetric recognition of spectral signatures of any archaeological material at different scale levels. Since 2016 she joined the research project Grandi Scavi Sapienza "Leopoli - Cencelle" under the scientific management of Prof. Francesca Romana Stasolla.
The work, started in 2016, has been developed in the different fields of the archaeological profession, finding application in both university research and freelance work. The work carried out in both fields took the form of drafting preventive archaeology reports and providing archaeological assistance during the work, focusing on excavation operations, collecting finds, filing, photographic documentation and archiving data, with particular attention to survey activities, using a combination of drone and other geodetic instruments, with the consequent stratigraphic analysis of structures and different types of archaeological strata. The scientific research was focussed above all on the topographical study of various Roman and medieval contexts in Latium, Umbria, Marche and Emilia Romagna and on the archaeological and architectural survey of various structures such as the walls of the city of Perugia and the "Porto Clementino" of the ancient city of Corneto - Tarquinia (VT).
