Marco Bardus, assistant professor in the Faculty of Health Sciences department of health promotion and community health, has spent his last 15 years at AUB exploring how digital technologies – cellphones, apps, laptops and others – can successfully promote health interventions. He has experimented with digital social marketing that targets individuals, families, or the entire community, always aiming to nudge citizens to adopt better health habits. The Covid-19 era, he explains, has opened new vistas of digital applications that can save time and money, and increase people’s access to health care.
