The power of personal health data

Individuals are tracking a variety of health-related data via a growing number of wearable devices and smartphone apps. More and more data relevant to health are also being captured passively as people communicate with one another on social networks, shop, work, or do any number of activities that leave “digital footprints.” Self-tracking data can provide better measures of everyday behavior and lifestyle and can fill in gaps in more traditional clinical or public health data collection, giving us a more complete picture of health.

If you are interested in learning more about the Network please contact us and let us know who you are, along with your suggestions for things that we should address.


We at the Health Data Exploration project are creating a Network of innovators in PHD to catalyze the use of personal data for the public good. This Network will bring together companies, researchers, and strategic partners to strategize, coordinate, and experiment with using PHD to understand health.
