About the position

The Department of Electronic systems (IES) is looking for a PhD candidate in the area of dynamically updated digital twins for a sustainable and carbon-neutral mobility future. A digital twin is defined as a virtual representation of a physical asset or process enabled through data and simulators for real-time prediction, optimization, monitoring, control, and improved decision making. For real-time operation, the twin requires continuous updating with new measurements from its observation platforms. However, all observations are not equally time-critical, and not equally important for the twin. This PhD will focus on the coupling between the twin and the different kinds of sensors, and will work with pre-processing, optimization and communication strategies to support accurate twin operation using limited communication resources. Machine learning and AI-based strategies that learn and adapt to the characteristics of the sensors, and the requirements of the twin will be of special interest.

The PhD position is part of a new large interdisciplinary initiative called Mobility Lab Elgeseter. The center is divided into the three focus areas 1) stakeholder needs for good mobility, 2) mobility as a system / transportation models, and 3) digital technologies for green mobility, that will work closely together to realize innovative and sustainable future mobility solutions in the urban environment. Within area 3) various enabling technologies will be used to automate the process of building and using digital mobility infrastructure twins (i.e. holistic/unified, life cycle, hierarchical, integrated, dynamic/updated representations of the physical road network) for collaboration, simulation, carbon/energy footprint calculations, road condition monitoring, predictive maintenance, automated traffic management and other forms for value creation (general knowledge will be developed that can be scaled up and used elsewhere).

To realize the objectives of focus area 3) several PhD candidates with partly overlapping competences will work closely together, each focusing on one of the following technology areas: 1) baseline Digital Mobility Twin (DMT) using site surveys and available geo-located data, 2) dynamically updated DMT using IoT, sensors, 5G and edge computing (this PhD position), 3) BigData and AI to create value from all the sensor data sent from the physical twin, e.g. in the form of decision support and automation, 4) autonomy and simulation  to train AI agents and simulate “what-if” scenarios, and 5) XR and Visualization to interact with the DMT throughout its life-cycle (construction and use) and increase citizens engagement and feedback before things have been built physically.

Throughout the overall Mobility Lab Elgeseter project there will be tight interaction with the other two focus areas, e.g. providing sensor data and visualizations to the two other areas, get feedback from area 1) regarding user needs and integrate transportation models from 2) in the DMT.

This PhD project is also part of the PERSEUS doctoral program that will contribute to a smarter, safer, and more sustainable future by approaching important challenges within key enabling technologies (Big data and AI, Digital Twins, Internet of Things, Extended Reality, and Information and Cyber Security). PERSEUS is a collaboration between NTNU, 11 top-level academic partners in 8 European countries, and 8 industrial partners within sectors of high societal relevance. The PERSEUS PhD candidates will have the opportunity to collaborate with researchers in the partner institutions and in other project consortia, and benefit from these collaborative research and education activities. This includes a 2–3 month international stay and a 1-2 month national stay with one of the PERSEUS partners.

The position's working place is NTNU campus in Trondheim.

You will report to your main supervisor.

We look forward to welcome you to the PERSEUS team.
