The Faculty of Technology, Natural Sciences and Maritime Sciences have a vacancy for a position as PhD Research Fellow in Ultrasound Tranducer Technology

About the position

The Faculty of Technology, Natural Sciences and Maritime Sciences has a vacancy for one position as PhD Research Fellow in ultrasound transducer technology.

The positions are located at the Department of Microsystems and reports to the Head of Department. The place of employment is USN Campus Vestfold, located at Bakkenteigen between Tønsberg and Horten.

The PhD project is part of the research center "Center for Innovative Ultrasound Solutions", CIUS. This is a Center for Research-based Innovation (SFI) appointed by the Norwegian Research Council where industry, healthcare providers and academia collaborate to develop the next generation of ultrasound solutions. For more information, see the CIUS web site http://www.ntnu.edu/cius. All research done in CIUS is industry-orientated, and the candidates will work in close contact with partners from the Norwegian industry.

About the PhD-project

USN has an active ultrasound research group centred around ultrasound transducer laboratory on Campus Vestfold. The new PhD candidate will be part of this research group. The group consists of one professor, one adjunct professor (20%), four PhD-students and a varying number of master students. We publish our results in international scientific journals and work closely with industrial partners. Our research topics are design, fabrication and characterization of ultrasound transducers for use in medical diagnostics, underwater sonar and industrial inspection. A tentative topic for the announced PhD-position is piezoelectric transducers for very high temperatures, aimed at inspection of industrial processes and in geothermal wells.

Central topic of the PhD-project will be:

  • Design, theoretical modelling and computer simulation of novel ultrasound transducer concepts
  • Fabricate and test novel ultrasound transducer concepts in the laboratory
  • Compare theoretical end experimental results
  • Interact with industry and research partners to discuss requirements, challenges and solutions for real-life application of the transducers

The appointment is for a period of three years. The position does not include teaching duties.


Applicants to the PhD position must have a Master’s degree (120 ECTS) equivalent higher education qualifications in physics, electronics, cybernetics, mathematics, micro- and nanotechnology or a related field. The degree must be accomplished before application deadline, and with degree B or higher.

It is a requirement that the successful applicant is granted admission to the university’s doctoral programme in Applied Micro- and Nanosystems within three months of accession in the position. For admission to the Programme the weighted average grade is B or higher is usually required.

Co-operation between staff members is an integrated part of the working atmosphere at the University of South-Eastern Norway. The candidate must be motivated and demonstrate a proven ability to work effectively within a team and in a collegiate manner to formulate and realize common objectives.

Personal suitability for the position will be emphasized. The PhD-candidate will be part of an active research group. He or she is expected to interact with the group members through discussions and meetings, to give and receive assistance in theoretical and practical challenges and to collaborate with external academic and industrial partners. The candidates must participate in and present their work at the bi-annual CIUS conferences.

Specific requirements for this position is:

  • Strong skills in physics and mathematics, knowledge of mechanics and electrical circuit theory
  • Knowledge of wave physics. Background in acoustics is preferred, but knowledge of electromagnetic waves, quantum physics, fluid mechanics, elasticity or similar can compensate for this
  • Experience with software tools for computer modelling and simulation. The ultrasound transducer lab uses MATLAB and COMSOL Multiphysics. Familiarity with these or equivalent tools is an advantage
  • Knowledge of piezoelectric theory is an advantage

In addition to the specific requirements above, evaluation of the candidates will be based on documented qualifications in the following fields:

  • Good analytical and theoretical skills
  • Good laboratory skills
  • Good English language presentation and writing skills
  • Knowledge of a Scandinavian language is an advantage
  • Ability to collaborate and interact in a research group and with external partners

Applicants are required to provide evidence of good English language skills, written and spoken. Applicants outside the Scandinavian educational system may use the following tests as such documentation: TOEFL, IELTS, Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Profiency in English (CPE).

We offer

  • A stimulating and growing research environment, with good opportunities to develop your career and your academic skills
  • A good social environment
  • Attractive welfare benefits in the State Pension Plan
  • Opportunity for physical activities within working hours


PhD Research Fellow (code 1017): NOK 482 200 a year. Further promotion will be based on time served in the position.

In special cases, employment in code 1378: NOK 482 200 - 618 600 a year may be considered.

A statutory contribution to the state pension plan will be deducted from the employee’s salary.
