Karl-Göran Sjögren, Senior researcher, Associate Professor in Archaeology University of Gothenburgh, Sweden, is born 1949, and has a BA from 1949, Ph.D. in archaeology from the University of Gothenburg from 2003 (”Mångfalldige uhrminnes grafvar….”. Megaliter och samhälle i Västsverige). He became an associate professor 2008. His main interest are megalithic monuments, Stone Age archaeology focusing on social transformation, but also the integration of science and databased methodology into archaeology (GIS, statistcs, isotops analysis etc).
T. Douglas Price (PhD 1975 University of Michigan) was Weinstein Professor of European Archaeology, Emeritus, and Director of the Laboratory for Archaeological Chemistry at the University of Wisconsin-Madison, where he has served on the faculty for more than 35 years. He is currently an honorary professor in the Department of Prehistory at the University of Aarhus. His field research has involved the investigation of the beginnings of agriculture on the island of Zealand, Denmark. A second area of interest involves archaeological chemistry and the use of isotopes in human tooth enamel to examine questions of prehistoric mobility. Major projects along these lines are focused in Central America, the North Atlantic, North America, China, and Europe.
The Laboratory for Archaeological Chemistry is also involved in the chemical analysis of ceramics, bone, soils, and other archaeological materials. He is the author or editor of more than 170 articles and 15 books, the most recent of which include Pathways to Power (with Gary Feinman, 2010), Introduction to Archaeological Chemistry (with James H. Burton, 2010), The Origins of Agriculture: New Data, New Ideas (with Ofer Bar-Yosef, 2011), Images of the Past 7e (with Gary Feinman, 2012), and Europe Before Rome (2012).
