Justin Leidwanger’s research and fieldwork focus primarily on the role of maritime networks in structuring Roman socioeconomic life. These interests lead him to spend more time in, rather than around, the waters of the Mediterranean, where his fieldwork explores the shipwrecks and ports that provide primary archaeological evidence for the modes and mechanisms of communication and exchange. In 2012, he initiated the Marzamemi Maritime Heritage Project, which combines survey and excavation with maritime heritage education and museum and tourism development at the site of several ancient shipwrecks off southeast Sicily, a focal point of which has been recent excavation of the famous late antique Marzamemi “church wreck”. Since 2011, he has co-directed annual investigations in the Archaic through late Roman harbors of Burgaz, off the Datça peninsula in southwest Turkey, with Elizabeth S. Greene (Brock University) and Numan Tuna (Middle East Technical University). Prior to this, he directed maritime landscape surveys off the coast of Cyprus (2003-2009). Over the past six years, he has been involved in issues of ethical stewardship, responsible management, public involvement, and collaboration in maritime archaeological investigations. On this topic, he has co-authored a number of recent articles and co-organized a series of international workshops and conferences in collaboration with the Penn Cultural Heritage Center, where he is active as a Fellow. In the Classics Department, he teaches courses on Roman archaeology, Greco-Roman architecture and engineering, Mediterranean seafaring and network connectivity, archaeological ethics, and the ancient economy. As faculty at the Stanford Archaeology Center, his lab serves as a research base for field projects as well as a center for pottery analysis (petrography and portable XRF).
