    William and Eva Price Senior Fellow at the Woods Institute for the Environment and Professor, by courtesy, of Oceans

    BioJim Leape is the William and Eva Price Senior Fellow in the Stanford Woods Institute for the Environment. He also serves as co-director of the Center for Ocean Solutions. Through research, writing and direct engagement with private and public sector leaders, Jim looks at how to drive large-scale systemic shifts to sustainability, with particular interest in expanding private sector leadership on sustainability globally.

    Jim has more than three decades of conservation experience, spanning a broad range of conservation issues on every continent. From 2005 to 2014, he served as Director General of WWF International and leader of the global WWF Network, which is one of the world’s largest conservation organizations, active in more than 100 countries. In that capacity, he worked with government, business and civil society leaders on a wide range of issues, including climate change, marine conservation, forest protection, water resources management, and sustainability in global commodity markets. Before going to WWF International, Jim directed the conservation and science initiatives of the David and Lucile Packard Foundation, a leading philanthropy in the U.S. Previously, he served as executive vice president of WWF-US in Washington, D.C.; as a lawyer for the United Nations Environment Programme in Nairobi, Kenya; as a law professor; and as a litigator for the National Audubon Society and for the U.S. Department of Justice.

    Jim serves on the boards of the Marine Stewardship Council, Mission 2020 and the Luc Hoffmann Institute, and on the Global Future Council for the Food Security and the Environmental Stewards Board of the World Economic Forum. From 2007 to 2017, he was a member of the China Council for International Cooperation in Environment and Development, which advises the Premier of China. He is also a Distinguished Fellow at the ClimateWorks Foundation.

  • Justin Leidwanger

    Justin Leidwanger

    Associate Professor of Classics and, by courtesy, of Oceans

    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.

  • Richard Luthy

    Richard Luthy

    Silas H. Palmer Professor of Civil Engineering and Professor, by courtesy, of Oceans

    Current Research and Scholarly InterestsDick Luthy studies sustainable solutions to urban water supplies and management of contaminated sediments. Current work includes experimentation and systems-level analysis of innovative, decentralized water reuse and management of urban stormwater for water supply. He is working with a group to assess strategies for coping with reduced water imports and requirements from the State's Water Board to leave more water in California rivers for ecosystems.
