Original Release Date: June 26, 2017

In episode ten of Just Science, we spoke with Dr. Gwyneth Gordon, from Arizona State University. Dr. Gordon and her team have developed methods to use the isotopic abundance of elements in hair to learn more about the history of an individual. This NIJ funded research, used in the investigation of unidentified dead, isotopic analysis will measures strontium, trace elements, and even rare earth minerals to shed light on diet, birthplace and residential history.

This episode of Just Science is funded by the National Institute of Justice’s Forensic Technology Center of Excellence [Award 2016-MU-BX-K110].
