Stephen Acabado is professor in the Department of Anthropology and an anthropological archaeologist interested in human environment interaction and indigenous response to colonialism. He is a strong advocate of an engaged archaeology where descendant communities are involved in the research process. His archaeological investigations in Ifugao, northern Philippines, have established the recent origins of the Cordillera Rice Terraces, which were once thought to be at least 2,000 years old. His work revolves around agricultural systems, indigenous responses to colonialism, subsistence shifts, landscape archaeology, and heritage conservation. He directs two archaeological projects in the Philippines: the Ifugao Archaeological Project and the Bicol Archaeological Project. In 2020, he is collaborating with Taiwanese colleagues in launching the Taiwan Indigenous Landscape and History Project.
