Arthur Andrew Demarest is an American anthropologist and archaeologist, known for his studies of the Maya civilization.
Demarest, a Louisiana Cajun, studied Mesoamerican anthropology and archaeology at Tulane University, where he graduated Summa Cum Laude and was awarded the Dean's Medal. Demarest earned his M.A. and doctorate in anthropology and archaeology at Harvard University, he held the endowed Danforth Chair in Archeology, and was elected to the prestigious Harvard Society of Fellows club. From 1984 to 1986 he served as Assistant Professor at Vanderbilt University in Tennessee, USA. In 1986 he was promoted to Full Professor and was named to the endowed Centennial Chair. He now holds the endowed chair of Ingram Professor of Anthropology and is the Director of Mesoamerican Archaeology and Development.
Demarest has worked in Mesoamerica for over 35 years, leading archaeological excavations and investigative expeditions every year. He is considered one of the world's leading experts on the Maya, but is also interested in the Olmec, Incas, Aztecs and many aspects of anthropological theory, particularly the collapse of civilizations, the role of religion in ancient societies, and ethics in anthropology. He currently divides his efforts between archaeological excavations and exploration, development programs for indigenous Maya communities, and management of the Vanderbilt-owned, but Maya-managed, Cancuen tropical forest and archaeological park in the Peten region of Guatemala. He is currently director of both the Vanderbilt Cancuen Regional Archaeological project in the Peten forest of Guatemala and the Vanderbilt/Universidad del Valle San Andres Semetabej Regional Archaeology and Development projects in Guatemala's volcanic highlands.
