Tricia Coletto
Archaeologist
Tricia is a field and research archaeologist, who has been working with the Gebel el-Silsila Project since 2016. After earning her Master of Arts in Archaeology and Heritage Management from the University of Exeter in 2013, Tricia first gained extensive experience in the field working at an Early Bronze Age settlement and a Roman Legion Camp before joining the Gebel e-Silsila mission.
Tricia's work focusses on several sites, including the 18th Dynasty and Roman Necropolises; the Thutmosid-Roman Temple of Kheny; the quarry of Amenhotep III; and the Tutankhamun workers village. In addition to large scale and comprehensive excavation, Tricia’s duties encompass all aspects of the mission’s work such as: tomb identification; landscape analysis; site survey and documentation; and small finds and artefact analysis, registration, and photography.
Tricia has presented the team’s work through professional conference papers and public presentations.
Tricia founded Meet the Archaeologist, an educational program designed to introduce school children and interested general audiences to the wonders of archaeology and the ancient world. She believes that through archaeology we open a door and get a glimpse of the distant past, the shared past of all humanity.

Tony Jibbefors
Archaeologist
Archaeologist Tony joined the Gebel el-Silsila Project in 2016, after I completing his Masters in Archaeology from Lund University.
An expert in 3D photogrammetry, Tony records and creates 3D models of graves, sites and finds. Tony works with the total station shooting point.

Barbara Veselka
Osteoarchaeologist
Barbara is a bioarchaeologist leading the study of the human remains of Silsila. I have completed a Masters in human osteoarchaeology and funerary archaeology. After a period as a freelance physical anthropologist I joined the University of Brussels.
Barbara examines the skeletons systematically assessing what’s there and draw what’s missing and making a note of the state of preservation. If possible Barbara estimates the age at death, sex and any pathological anomalies. I found some individuals that seem to have vitamin D deficiency which is remarkable for a country like Egypt with so much sunlight.
