The appointment is for a period of three years (with possibility of one-year extension) for a candidate with knowledge, skills and will to successfully complete the PhD study within and limited to the time frame.

The PhD position is for a fixed term, with the objective of completion of research education to the level of a doctoral degree. Admission to a PhD programme is a prerequisite for employment, and the programme period starts on commencement of the position. The PhD Candidate shall participate in the Faculty’s organized research training, and the PhD study shall be completed during the period of employment. Information about the application process for admission to the PhD programme, application form and regulations for the degree of Philosophiae Doctor (PhD) are available at the Faculty’s website for Research training.

Further information about the position is available by contacting: Associate professor Phuong Hoai Ha (

The Arctic Green Computing (AGC) research group ( aims at addressing energy efficiency, system complexity and dependability across mobile, embedded and data-center systems. The group current research topics include novel execution models for energy-efficient computing and analytics. The group was a work-package leader in EU FP7 ICT project EXCESS on energy-efficient high-performance computing systems (2013 – 2016), and is PI and Co-PI of several national research projects funded by the Research Council of Norway (including FRIPRO Young Research Talents, Research Infrastructure and IKTPLUSS initiative). The group is the Norwegian representative in the management committee of the EU COST Action Euro-TM on concurrent programming abstractions (2011 – 2015) and a member of EU network of excellence HiPEAC on high performance and embedded architecture and compilation.

The research project

The arctic tundra is a demanding region with severe weather, low temperatures, limited network services and energy, and often being physically inaccessible. This project advances the state of the art for cyber-physical systems being exposed to such extreme conditions. The Distributed Arctic Observatory is a novel next-generation scalable, energy sensitive, configurable, and robust observation system enabling many in-situ observations at high resolutions and at many locations throughout the arctic tundra, and with services making the data available and explorable by researchers and the public.

There are many challenges facing such a system. Observation units have to use their limited resources in an energy sensitive way. Especially the analytics processing to find interesting objects in the observed data requires increased energy efficiency. To be useful in practice the system must be adaptable to new needs, and provide for access to data and for practical analytics and visualizations

To address the energy limitation challenge, the project will develop new methodology and frameworks to utilize the computing power of local observation units to do energy-aware scheduling of the use of the resources of an observation unit. This includes being able to autonomously do trade-offs between the frequency of observations, type of observations, local processing and frequency of reporting. We will also devise new, and improve existing big data analytics techniques, including deep learning, to increase their energy efficiency by an order of magnitude to make them suitable to be used on in-situ observation units with a limited power budget.

Qualification requirements

The successful applicant must fulfil the requirements for admission to the Faculty’s PhD programme; cf. Regulation for the degree of Philosophiae Doctor (PhD) at the University of Tromsø. The applicant should in addition be able to document proficiency in English equivalent to Norwegian Higher Education Entrance Qualification, available at the same website.

This position requires a Master’s degree or equivalent in Computer Science.

A successful candidate should have a strong interest in at least one of the following topics: energy-efficient computing, energy-efficient communication, energy-harvesting, edge computing, programming abstractions and run-time systems. Experience of mixed criticality systems and data analytics at the edge devices is an advantage. Since our research results are evaluated experimentally, good programming skills are necessary.

Emphasis shall also be attached to personal suitability.

Working conditions

The normal period of appointment is three years (with possibility of one-year extension). The PhD study is standardized to three years. The possible fourth year consists of teaching or other duties for the university, organized according to a distribution formula of 25 % per year in agreement with the Head of Department, cf. the directive for duties for research fellows (in Norwegian only).

A shorter period of appointment may be decided when the research fellow has already completed parts of his/her research training program or when the appointment is based on a previous qualifying position (PhD Candidate, research assistant, or the equivalent) in such a way that the total time used for research training amounts to three years.

Remuneration for the position of PhD Candidate is in accordance with the State salary scale code 1017. At present, the gross salary starts from NOK 436.900 per year. A compulsory contribution of 2 % to the Norwegian Public Service Pension Fund will be deducted.


The applicants will be assessed by an expert committee. During this assessment process, emphasis will be attached to the applicant’s potential for research as shown by:

  • Publications
  • Master’s thesis or equivalent
  • any other academic works

The applicants assessed as the best qualified will be called to an interview. The interview shall among other things aim to clarify the applicant’s personal suitability for the position.
