The PhD defence will be partially digital, in Kristen Nygaards sal (5370), Ole Johan Dahls hus, and streamed directly using Zoom. The host of the session will moderate the technicalities while the chair of the defence will moderate the disputation.
Ex auditorio questions: the chair of the defence will invite the attending audience at Kristen Nygaards sal (5370), Ole Johan Dahls hus to ask ex auditorio questions.

Main research findings
5G and future 6G networks are expected to support everything from everyday mobile apps to time-critical services such as connected vehicles. In practice, however, delivering that consistently is difficult: network performance varies across time and location, and the growing mix of devices and applications increases the challenge of providing fast, reliable services. To meet strict delay requirements, networks increasingly rely on edge computing. With edge computing, computation is moved from distant cloud data centers to servers placed closer to users.
This thesis advances a data-driven design and implementation approach for efficient and sustainable edge computing. It starts by analyzing operational 5G data to capture realistic performance variability and mobility patterns. This helps avoid idealized assumptions. Building on this foundation, the thesis develops methods for planning and operating edge resources that balance delay, scalability, and cost under dynamic conditions.
The thesis shows that a layered edge infrastructure can support diverse services more flexibly than a single, uniform design. It also demonstrates how considering energy alongside delay influences system decisions that matter for sustainable next-generation networks. The result is a practical framework for building scalable edge systems that can support heterogeneous services in future mobile networks.
