Dr. Ackerman’s area of expertise is the Prehistory of Beringia (Alaska and Siberia). For doctorate studies at the University of Pennsylvania, Dr. Ackerman conducted archaeological investigations on St. Lawrence Island, which continued in Southern Alaska (Glacier Bay to Dixon Entrance) and Southwestern Alaska (Kuskokwim River drainage and associated uplands). Research visits also included sites in Siberia and the Russian Far East. The archaeological collections are at the Museum of the North at the University of Alaska with the bulk of the collections in the Museum of Anthropology collections at Washington State University. Dr. Ackerman’s first AAA Annual Meeting was in 1963.
