PhD Fellow in Distributed Acoustic Sensing for Arctic Railway Infrastructure Monitoring

The position

A PhD position is available at the Department of Electrical Engineering (IET), Faculty of Engineering Sciences and Technology, UiT The Arctic University of Norway. The position is within the field of distributed fibre-optic sensing for railway infrastructure monitoring, with particular emphasis on the use of Distributed Acoustic Sensing (DAS) for monitoring railway infrastructure and natural hazards along the Ofoten Line.

The position is for a period of four years. The nominal length of the PhD programme is three years. The fourth year is distributed as 25 % each year and will consist of teaching and other duties. The objective of the position is to complete research training to the level of a doctoral degree. Admission to the PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position.

The workplace is at UiT in Narvik. You must be able to start in the position within a reasonable time after receiving the offer.

The position’s field of research

Railway infrastructure in Arctic and Nordic regions is increasingly exposed to harsh weather, heavy traffic loads, climate-related hazards, and growing operational demands. Current railway monitoring systems still rely largely on manual inspections and periodic measurements. This makes it challenging to detect early signs of infrastructure degradation, vibration-related damage, geohazards, snow avalanches, rockfalls, landslides, track irregularities, wheel defects, bearing faults, and people and animals on the track.

The PhD project will investigate how existing fibre-optic cable infrastructure along the Ofoten line railway, one of Norway’s most strategically important and climate-exposed railways, can be used as a distributed sensor network for continuous infrastructure monitoring. Standard optical fibres will be used as dense arrays of vibration sensors, making it possible to measure dynamic strain and acoustic disturbances along many kilometres of fibre with down to metre-scale spatial resolution – a technique coined Distributed Acoustic Sensing (DAS). The long-term ambition is to enable high-resolution, real-time warning and decision support for railway operations and maintenance.

The successful candidate will work on developing, testing, modelling, and validating methods for DAS-based monitoring of railway infrastructure and surrounding terrain. The work can include physics-based modelling of e.g., various events and wave propagation through different media, signal processing, large-scale data analysis, algorithm development and potentially also field work.

The applicants must present a description outlining the academic basis of the PhD project. The project description shall not exceed 2 pages, including reference lists/figures/tables if relevant. It must include a description of the topic, research question(s) and a reasoning of the choices. It should also indicate the methodologies to be used. The final project description will be developed in cooperation with the supervisor.

Qualifications

This position requires a master’s degree or equivalent in applied mathematics, signal processing, physics, geophysics, civil engineering (electrical, geotechnical, structural, environmental, transportation, construction, computer etc.), data/computer science or similar. If you are near completion of your master’s degree, you may still apply.

Applicants must document good English skills and be able to work in an international environment. Nordic applicants can document their English capabilities by attaching their high school diploma.

The candidate should have expertise in data analysis and be able to implement data analysis tools in a suitable programming language. It is also advantageous with knowledge and/or capabilities in one or more of the following topics:

In the assessment, the emphasis is on the applicant's potential to complete a research education based on the master's thesis or equivalent, and any other scientific work. Evaluation of the candidate is not only based on the candidates track record in education, but other experiences that can be relevant for the PhD work. This includes teaching, practical experience with e.g., railway infrastructure and/or other relevant work or activities. The project description will also be considered. In addition, professional experience and other experience of significance for the completion of the doctoral programme will be taken into consideration.

We will also emphasize motivation and personal suitability for the position. We are looking for candidates who:

As many people as possible should have the opportunity to undertake organized research training. If you already hold a PhD or have equivalent competence, we will not appoint you to this position.

Admission to the PhD programme 

For employment in the PhD position, you must be qualified for admission to the PhD programme at the Faculty of Engineering Science and Technology and participate in organized doctoral studies within the employment period.

Admission normally requires:

In order to gain admission to the programme, applicants with a background from a Norwegian institution should have a minimum grade of C on their master thesis and a weighted grade average of 3.0 for the last two years of their master programme. A more detailed description of admission requirements can be found here.

If you are employed in the position, you will be provisionally admitted to the PhD programme. Application for final admission must be submitted no later than two months after taking up the position.

Applicants with a foreign education will be subjected to an evaluation of whether the educational background is equal to Norwegian higher education, following national guidelines from Norwegian Directorate for Higher Education and Skills. Depending on which country the education is from, one or two additional years of university education may be required to fulfil admission requirements, e.g. a 4-year bachelor's degree and a 2-year master's degree. UiT normally accepts higher education from countries that are part of the Lisbon Recognition Convention.
