Our group applies Electrical Engineering and Computer Science to create tools and platforms for Biomedical applications and Public Health. All over the world, mobile phones and the Internet of Things have been transforming our work as well as our personal lives. Coupled with intelligent algorithms, the devices in our environment are powerful instruments that augment our senses, predict our health, or simply to give us feedback and help guide our behavior. Like any tool, digital devices can be abused, and can also be addictive if self-agency is neglected. But in general, these ubiquitous computers have demonstrated enormous potential for empowering everyday people (patients, health workers, doctors, farmers, etc.) to perform extraordinary tasks in a wide variety of domains ranging from chronic disease and global health to mental health and drug addiction.
