As a research scientist at the MIT Design Laboratory, co-founder of the MIT/Harvard Large Scale Network Analysis Project, and a Postdoctoral Fellow at the Santa Fe Institute, Nathan Eagle understands how data from our cell phones and other mobile devices can be used to observe and predict the activities of individuals and groups, which he calls reality mining. He is the principal investigator for the EPROM project in Kenya, within the MIT Design Laboratory, and his PhD from the MIT Media Laboratory on Reality Mining was declared one of the 10 technologies most likely to change the way we live by the MIT Technology Review magazine.
