A Small Field, Not a Niche: A Portrait of Digital Public Health

The “Kleine Fächer” portal profiles disciplines that are represented by dedicated professorships at only a few institutions. Digital Public Health is one of them. However, the field is considered “small” primarily because it is young, not because it is marginal. The issues it addresses affect a great many people.

 

Public health focuses on the health of populations rather than on individual diseases. Digital public health applies this perspective to digitalization. Digital technologies—ranging from health apps to telemedicine to generative AI—are both the subject of study and a tool in this field. Christoph Dockweiler examines how these technologies are changing health behaviors, access to care, and the distribution of health opportunities, and how technology can be designed to promote health rather than exacerbate inequalities.

 

Just how relevant this is is demonstrated by one of his current areas of focus. Many people now ask their health questions to a system like ChatGPT, often before seeking medical advice. At the population level, this is changing how health knowledge is generated, circulated, and believed. For him, the real challenge lies not solely in the accuracy of individual answers, but in the fact that generative AI is shifting the very foundations of public health discourse—that is, the question of who is considered an authority and how societal consensus on health is formed.

 

In Siegen, the professorship is deliberately situated within the social sciences and is closely linked to computer science as well as the Center for Interdisciplinary Health Research (ZIGS). His conclusion is unequivocal.

 

“Digital public health should not be viewed as a niche, but rather as an infrastructure that an increasingly digital society needs for its health.” Christoph Dockweiler
