    BioJustin Leidwanger's work focuses on Mediterranean mobilities, interaction, and maritime heritage. Ships and ports, especially in southeast Sicily and southwest Turkey, are central to exploring these themes in the field, providing evidence for connections and the long-term dynamics that shaped communities amid the economically, socially, and politically changing worlds from the rise of Rome through late antiquity and beyond.

    Between 2013 and 2019, he led investigations of the 6th-century Marzamemi 2 “church wreck” (Sicily), which sank while carrying nearly 100 tons of marble architectural elements. Work continues through underwater survey, 3D analysis, and publication as well as immersive museum-based and pop-up exhibits and other initiatives. Project 'U Mari extends this collaborative and community-based field research across southeast Sicily, interrogating the heritage of diverse but co-dependent interactions with and across the sea that have long defined the central Mediterranean. These connections offer a resource for deeper critical engagement with the past, more meaningful identities in the present, and more sustainable development in the future. One facet of this work examines the socioeconomic dynamics spanning three millennia of tuna fishing through maritime landscape archaeology and documentation of the fading material culture and traditional knowledge of the mattanza. Another mobilizes archaeology to better understand the creation and circulation of plastics as maritime material assemblages, offering a window into socio-environmental systems. These efforts simultaneously foreground heritage activism through community-based archaeology of the spaces, materialities, and memories of contemporary journeys of forced and undocumented migration across these waters.

    Justin teaches courses and advises students on topics in Hellenistic, Roman, and Late Antique archaeology, Mediterranean heritage, economies and interaction, port networks, ceramic production and exchange, and Greco-Roman architecture and engineering. The Maritime Archaeology & Digital Heritage Lab (MEDLab) at the Archaeology Center serves as a fieldwork base and collaborative resource for digital modeling (structured light scanning, laser scanning, photogrammetry, GIS, network analysis) and pottery analysis (petrography, pXRF, computational morphological analysis).

    Author of Roman Seas: A Maritime Archaeology of Eastern Mediterranean Economies (Oxford), and editor or co-editor of five more volumes, including Regional Economies in Action (Vienna) and Maritime Networks in the Ancient Mediterranean World (Cambridge), he is currently working on two books. The first, entitled Fluid Technologies: Innovation on the Ancient Mediterranean, arises from research with students in the field, lab, and museum, analyzing transport amphoras, port infrastructure, and other clues to ancient technologies of distribution. The second, The Tuna Trap, explores the entanglement of mobilities that have and continue to bind the shores surrounding the Strait of Sicily.

    Ph.D. Student in Classics, admitted Autumn 2022

    BioI am broadly interested in the production of knowledge in ancient worlds, with a particular interest in the Greco-Roman and Chinese traditions. My curiosity is a comparative and genealogical one at root: by comparing different societies, I seek to grasp the historicity of intellectual practices and the ideas thus produced. Currently, my research interest focuses on astronomy and astrology in Ancient Greece and China.
    While completing my B.A. in Classics at Sorbonne University, I investigated how the urban metamorphoses of Rome materialized the transformation of the political regime. My master's thesis at EHESS, "Statues pour les corps, livres pour les mots" : La vie (βἰος) et la rhétorique (λόγος) dans les Discours Sacrés, offers insight into the psychosomatic relations conceived by the Greeks. The inquiry breaks into two interdependent questions: the therapeutic usage of rhetorical practices and the unconventional representation of Asclepius in the Sacred Tales of Aristides.
    Having one year of training in software engineering from Tsinghua University, I am also passionate about the potentials of digital humanities.
