I have worked extensively over the past 10 years in leveraging mobile phones as sensors and as a delivery platform in various domains ranging from Telematics, Health Care , mHealth and election fraud monitoring. A sampling of some the applications I have worked on can be found here http://android.calit2.net/group2/index_old.html Recently, I have been engaged with a few projects in Africa that uses feature phones via SMS and USSD. I am currently focussed on projects that will help spur the growth of mobile money in West Africa. One of the projects I am working on is with my colleague Dr. Claire Adida, on the use of mobile money to pay for school tuition in Benin. We recently made a week long trip to Benin forging partnerships with the Carriers and the schools to make this a reality.
