The Department of Anthropology Colloquium Series Presents
Determining the Origin of Human Skeletal Remains Using Stable Isotopes
Defense POW/MIA Accounting Agency (DPAA)
Thursday, January 23, 3:00 pm, Crawford Hall 115
Stable isotopes are "nature's recorders" and those recorded in human tissues, such as bones and hair, tell the story of a person's life: What did you eat? Where did you live? Answering these questions is possible because isotopes in tissues are related to the isotopes in drinking water and food, which vary based on geography, environment, cultural practices, etc. This presentation provides an overview of forensic isotope analysis, a relatively new investigative technique useful for the identification of human skeletal remains.
