Universitetet i Oslo

The University of Oslo is Norway’s oldest and highest rated institution of research and education with 28 000 students and 7000 employees. Its broad range of academic disciplines and internationally esteemed research communities make UiO an important contributor to society.


The Department of Informatics (IFI) is one of nine departments belonging to the Faculty of Mathematics and Natural Sciences. IFI is Norway’s largest university department for general education and research in Computer Science and related topics.


The Department has more than 1800 students on bachelor level, 600 master students, and over 240 PhDs and postdocs. The overall staff of the Department is close to 370 employees, about 280 of these in full time positions. The full time tenured academic staff is 75, mostly Full/Associate Professors..

Job description

Position as PhD Research Fellow in signal processing is available at the Group for Digital Signal Processing and Image Analysis, Section for Machine Learning, Department of Informatics, University of Oslo.

The fellowship period is 3 years. Starting date as soon as practical, no later than 01.10.2021. The position is in collaboration with Kongsberg Maritime AS through a project supported by the Research Council of Norway.

Kongsberg Maritime is a global marine technology company providing innovative and reliable technology solutions for all marine industry sectors including merchant, offshore, subsea and naval. Through the office at Strandpromenaden, Horten Kongsberg Maritime develops and produce sonars and echosounders which provide safe navigation of vessels and updated knowledge about the sustainability of ocean resources for future generations. The candidate will collaborate with the central technology department designing underwater acoustic systems, with leading experts in acoustics, electronics, embedded design and signal processing.

The Digital Signal Processing and Image Analysis research group has five full-time and six adjunct positions. We perform research over a wide range of applications in image analysis and deep learning, as well as in digital signal processing/acoustic imaging. There are about 25 Postdocs and PhD students in the group with financing from a variety of national and international sources, as well as from industry. More information can be found on the group’s homepage.

No one can be appointed for more than one PhD Research Fellowship period at the University of Oslo.

Job description

The position is in the Digital Signal Processing and Image Analysis (DSB) group. Your research will focus on developing signal processing for the next generation of sonars and echosounders. The project will build on two recent PhD projects.

Research task examples:

- Development of high-performance signal processing methods for sonars and echosounders.

- Development of advanced beamforming algorithms for sonar arrays.

- Design and use of simulated data to evaluate sonar systems and signal processing algorithms.

- Test and evaluate signal processing methods on state-of-the art Kongsberg Maritime equipment.

- Analysis and characterization of statistical properties to improve beamformer performance.

There will be opportunities to participate in field experiments.

The candidate is expected to publish research results in international peer-reviewed journals in collaboration with the DSB group and its research partners

A detailed research plan for the PhD period will be defined based on both the project objectives and the candidate’s background.
