John “Mac” Marston is a professor of Archaeology and Anthropology. He is the director of Boston University’s Archaeology Program and holds a Ph.D. from the University of California, Los Angeles. He is an environmental archaeologist who studies the long-term sustainability of agriculture and land use, with a focus on ancient societies of the Mediterranean and western and central Asia. His research focuses on how people make decisions about land use within changing economic, social, and environmental settings, and how those decisions affect the environment at local and regional scales. A specialist in paleoethnobotany, the study of archaeological plant remains, Marston’s contributions to the field include novel ways of linking ecological theory with archaeological methods to reconstruct agricultural and land-use strategies from plant and animal remains.
