Dr. Linus Bengtsson - a clinical epidemiologist – discussed his work with mobile phone networks to effectively track population movements following the Haiti Earthquake. The data collected assisted the more efficient distribution of humanitarian relief to populations in need. His new organization, Flowminder, based in Stolkholm Sweden, is establishing a global clearinghouse for aggregating, analyzing, and disseminating anonymized mobile phone location data to NGOs and relief agencies during disaster relief and reconstruction efforts.
