Mobile Health Systems Lab

At the mHealth Systems lab, we strive to make a difference in people's lives via sound research via sound research.
Our current work (supported by the NIH Center of Excellence for Mobile Sensor Data-to-Knowledge (MD2K)) seeks to define new frontiers in the newly emerging discipline of mobile health (mHealth). With support from the prestigious Genes Environment Initiative (GEI) at the National Institutes of Health (NIH), we developed the AutoSense wearable sensor system to continuously monitor physiology in the mobile environment. AutoSense is complemented by a software framework on the mobile phone called FieldStream (supported by the NetSE program at NSF) that collects physiological measurements from AutoSense sensors, processes them to make behavioral inferences, and uses these behavioral events to solicit self-reports on the phone, all in real-time. The entire end-to-end system has been worn by 100+ human volunteers (including daily smokers, drinkers, and drug users) for 10,000+ hours in their natural environments as part of various scientific user studies. From these real-life sensor measurements, we have developed robust models to automatically infer psychological stress, to detect conversation episodes, to detect smoking puffs, and detect cocaine use in field.
