Trust in Digital Services

Research Profile

Platform Economy

Digital platforms are becoming increasingly important. As the world's leading business model, three of the five largest listed companies are based on a platform approach. Our research focus in this area is the analysis and design of digital platform ecosystems.


Human-Computer Interaction

A look at today's digital landscape shows that the presence of computer agents in daily life has increased steadily over the last two decades. These computer agents interact with humans in different contexts. A better understanding of the specific interaction between humans and computer agents is therefore of utmost importance.



Crowdfunding is an Internet-based financing and investment instrument in which a large number of private individuals contribute to the financing of projects through individually small amounts. The possibility for users to see the actions of others gives rise to complex mechanisms, including so-called herd behavior. This and other social mechanisms within the crowd form our research focus in this area.


Online Trust & Reputation

Simply put, trust is the willingness to depend on others. It plays a special role in the context of digital platforms. We focus on investigating which elements or forms of presentation of an online platform create trust - both among customers and merchants.


Trust in Artificial Intelligence (AI)

Artificial intelligence (AI) and machine learning (ML) have become increasingly important tools to support human decision making in various domains. In an increasing number of applications, ML-trained algorithms are reaching levels of performance comparable to or exceeding that of humans. However, given this rapid progress in cognitive automation, the role of human decision makers is an often overlooked factor.


Information Bubbles

Filter or information bubbles refer to a state of intellectual isolation in which only certain information is processed. The term refers primarily to the consumption of online news and press articles, but also to the perception of opinions and posted content from friends and acquaintances in online social networks.
