Today, Tobias Kowatsch gave a keynote at the HSG Highlights, an executive programme of the University of St.Gallen. Dr. Kowatsch gave an overview of digital health interventions, focusing on strategies to reach and engage vulnerable individuals. He highlighted that it is of utmost importance to use technology to target this group, as individuals with lower socio-economic status are substantially more affected by non-communicable diseases in developed countries. A big thanks goes to Prof. Dr. Oliver Gassmann for his invitation.
