Global Public Health (GPH) is the science of protecting and improving population health on a global, multi-country scale based on the Essential Public Health Functions (EPHFs). These central functions are a guiding force for public health and aim for health equity, population participation and inter-sectoral governance models. Global public health thus supports and complements personalized healthcare. The Chair for Digital Global Public Health at HPI aims to use data-driven digital applications and dedicate its research and activities towards disease prevention and population-level health promotion while improving circumstances (e.g., access to digital health) and health behavior within and across communities.
