The SFB cordially invites you to the oral examination for Niklas Strüver’s doctoral dissertation.

Monday, July 27, 2026, at 11:00 a.m. in Room AH-A 217/18.

During the defense, the findings of his dissertation will be presented to the examination committee and academically defended. The title of his dissertation is “Speaking on behalf of the periphery: Third-party relationships in Amazon’s Alexa ecosystem” and it examines the developmental dynamics of the voice assistant Alexa from the perspectives of infrastructure and platform theory. Drawing on the four articles presented, the dissertation explores how Alexa functions as an infrastructure and platform for third-party providers in business and academia, and what sociotechnical power imbalances arise in the process. This analysis allows for an examination of the social relationships that Amazon, as the manufacturer, enters into with complementary providers on the periphery of the platform. Through various empirical approaches, it is possible, despite the usual secrecy maintained by large corporations, to gain insight into the development of technologies that are present in the everyday lives of many people.

It will be conducted in German and supervised by the two examiners, Dagmar Hoffmann and Armin Beverungen.
