I research and teach space archaeology and Mediterranean art and archaeology and I am listed in the Register of Professional Archaeologists. I have worked on excavations in the United States, Spain, Jordan, and Italy since 1998. In 2014, I began a new collaborative project on the Iberian indigenous settlement of Cástulo, Spain. I have also worked to develop the emerging field of space archaeology. Together with my co-PI, Dr. Alice Gorman (Flinders University), I am leading the first large-scale archaeological investigation of a human habitation site in space: the International Space Station.
My other work includes problems related to cultural heritage management and the use of digital technology in art history and archaeology.
