As I wrap up my year-long sabbatical in Switzerland, during which I was a visitor at ETH Zürich, I am grateful to have been part of the innovative team at the Center for Digital Health Interventions (CDHI). Led by Profs. Elgar Fleisch and Tobias Kowatsch and jointly operated by ETH and the University of St. Gallen, the center is working on a range of important problems, interesting studies, and innovative technologies: passive health-sensing techniques in smartphones, smartwatches, and cars; stress detection; asthmatic cough detection and breathing-exercise games for asthmatics; machine learning to predict when a person might be receptive to health-intervention messages; chat bots to engage and encourage people involved in health interventions; systems to detect hypoglycemia in the driver of a car; passive interventions that can occur while driving; and more.
Although my visit has been scientifically productive and rewarding, it is really the people who have made the visit so delightful. The faculty welcomed me by encouraging and enabling me to be involved wherever I seemed interested; my officemates patiently answered all my questions about Zürich and Switzerland; the graduate students adopted me into their lunchtime group outings; and the staff assisted me with all the complex logistics of moving to, living in, and departing from Switzerland. Just a portion of the team is pictured below. I am proud to have been part of this group for the past year, and hope I can return again some day!
