Justin Leidwanger
Associate Professor of Classics and, by courtesy, of Oceans
BioJustin Leidwanger's research focuses on Mediterranean mobilities and connectivity, maritime livelihoods, and their heritage. Ships and ports are central to exploring these themes, providing evidence for the long-term dynamics that shaped coastal communities economically, socially, and politically. He is drawn to the long arc of the Roman Mediterranean, especially its temporal edges, from the emergence of Hellenistic states to the long Late Antiquity and beyond. Through a focus on diverse but co-dependent seaborne interactions that have and continue to define the Mediterranean, this work aligns critical engagement with the past, advocacy for local communities in the present, and sustainable development for the future.
Current collaborative fieldwork in Sardinia with the University of Sassari examines the socio-environmental dynamics spanning three millennia of tuna trap fisheries (tonnare). In Croatia, joint excavation with the Croatian Conservation Institute of a wreck carrying a high-ranking individual and perhaps a goldsmith around 700 CE sheds new light on the transformation of interactions at the end of antiquity (featured in National Geographic, Reuters, and elsewhere). A maritime landscape survey with Dokuz Eylül University in southwest Türkiye explores the impacts of early Hellenistic sociopolitical shifts on local economies and mobilities.
Previously, Justin co-directed investigations (2011-2015) at the Archaic through Late Antique harbors of Burgaz (“Old Knidos”) in Türkiye, and led excavations (2013-2019) of the 6th-century Marzamemi 2 “church wreck” off Sicily, which carried 100 tons of marble architectural elements. Work in Sicily continues through 3D and other analyses of the assemblage as well as immersive museum-based and other heritage initiatives that link past and present. One facet of this work mobilizes archaeology to understand the creation and circulation of plastics as maritime material assemblages, offering a new vantage point on socio-environmental systems. Another uses archaeology to foreground heritage activism through the spaces, materialities, and memories of forced and undocumented migration across these waters.
On campus, he 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, archaeological theory, 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 shipwreck and harbor archaeology, digital modeling (structured light scanning, laser scanning, photogrammetry, GIS, network visualization), and pottery analysis (petrography, pXRF, computational morphological analysis, finite element method, experimental archaeology).
Author of Roman Seas: A Maritime Archaeology of Eastern Mediterranean Economies (Oxford), and editor or co-editor of various volumes, including Maritime Networks in the Ancient Mediterranean World (Cambridge), Regional Economies in Action (Vienna), and Across the Shore: Integrating Perspective on Maritime Heritage (Springer), he is currently working on two books. The first, Fluid Technologies: Innovation on the Ancient Mediterranean, examines the interdependence of maritime logistics in Greco-Roman economies, from transport amphora standardization to changes in ship design and port infrastructure. The second, The Tuna Trap, uses the distinctive practices surrounding community fisheries to shed light on the entanglement of human and non-human mobilities across central Mediterranean waters. -

Paul Lendway
Postdoctoral Scholar, Political Science
BioI am a Postdoctoral Scholar at Stanford University, specializing in American politics and political economy. In May 2025, I graduated with a Ph.D. in Political Science (with departmental distinction) from Yale University. In 2026, I was selected to receive two awards from the American Political Science Association: the Distinguished Junior Scholar Award in Political Psychology and the Wildavsky Award for Best Dissertation in Religion and Politics. My research is published or accepted in the American Journal of Political Science, Political Behavior, American Politics Research, the Journal of Conflict Resolution, Environmental Politics, Research & Politics, and the Yale Journal of International Affairs. Additionally, my co-authored research is conditionally accepted at the Journal of Politics.
The norms and rules that comprise American democracy are eroding. Why? What are the consequences of this trend? And what can be done to address this issue? My research program aims to address these questions. One stream of my research investigates how various forms of political communication (i.e., sermon rhetoric, populist appeals, etc.) shape political preferences. Another strand of my research probes the role of information (i.e., information about social movements, inequality, AI, etc.) in structuring public opinion and policy preferences. A final line of my research explores solutions to address the pressures of populism and mass polarization. This includes a project that tests Americans' willingness to compromise on a series of multi-dimensional policy tradeoffs (i.e., a conservative immigration policy and a liberal abortion policy, etc.).
