How is trust created between buyers and sellers on the Internet? Professor Dr. Timm Teubner, newly appointed to Technische Universität Berlin and the Einstein Center Digital Future (ECDF), conducts his research into this question from a perspective informed by sociology and economics. From 2004 to 2010, Teubner studied industrial engineering at the Karlsruhe Institute of Technology, where he also completed his doctorate and subsequently worked as a postdoctoral researcher. He spent one year studying at the University of Massachusetts (UMass) in the USA. Professor Teubner, Chair of Trust in Digital Services at Faculty VII, is looking forward to continuing his research into digital platforms from A (as in Amazon) to Z (as in Zalando), taking advantage of the interdisciplinary framework of the ECDF.
