Mobile phones are being used to collect data for a variety of different disciplines and SFI Omidyar Fellow, Nathan Eagle, is studying human movement and behavior through mobile phones. In an experiment at MIT, Eagle studied call logs of 100 students and staff and found he could sort the business students from other majors with 96% accuracy. Eagle is going to experiment on a larger scale next by studying millions of mobile phone users throughout Europe and parts of East Africa. Part of his study is to see if certain phone behaviors can help alert public health officials in the early stages of disease outbreaks.
