Postdoctoral Fellow in Experimental Fluid Mechanics: Wave-turbulence Interactions

About the position 

We announce a 4-year postdoctoral fellowship as part of an ERC project, for experimental work in the one-of-a-kind water channel facility  at NTNU Trondheim, Norway. The experiments will be unique in combining tailored waves, turbulence and mean flow simultaneously. This is a rare opportunity for an excellent candidate with experimental background to work in a highly active, ambitious, multinational research team in a stimulating environment.

You will work in the group led by Professor Simen Å. Ellingsen.  

The project WaTurSheD, funded by the European Research Council (ERC), concerns the triple interactions of waves, turbulence and shear currents (WTC) and how they mix waters beneath a water surface. How heat and gas are mixed into the ocean is crucial to ocean and climate modelling, but the underlying physics are not well understood, something the project will address; thus, the research is a scientifically exciting study of fundamental fluid mechanics, and important to our future.

The postdoctoral fellowship position is a temporary position where the main goal is to qualify for work in senior academic positions.

You will be responsible for an extensive laboratory campaign in the Large Water Channel (Jooss et al. 2020, J. Fluid Mech. 911, A4 ), in close collaboration with several other postdocs and PhD students.

The applicant should include a brief research proposal of no more than one page (see below).

Duties of the position

• Planning, preparing, and executing state-of-the-art experiments
• Some management and supervision tasks in the research group, including preparation of article manuscripts
• Some minor departmental and teaching tasks

Required selection criteria

• You must have completed a Norwegian doctoral degree or corresponding foreign doctoral degree recognized as equivalent to a Norwegian PhD in physics or mechanical engineering. If you can document that the PhD thesis will, in all probability, be obtained before the announced start-up date, your application can be assessed even if you have not yet defended your dissertation. Documentation of the obtained doctoral degree must be presented before you can take up the position.
• Extensive experimental research experience in a relevant branch of the physical sciences at a level publishable in high quality international journals is an absolute requirement.
• Excellent English language skills, including documented skill in independent scientific writing (e.g., article manuscripts). A responsibility of the position will be to help bring manuscripts within the research group up to a publishable standard.
• A strong international publication record in highly reputable journals, with emphasis on quality over quantity.

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Ph.D Candidate, research assistant and specialist candidate  (in Norwegian). 

Preferred selection criteria

• Experience with experimental fluid mechanics is a clear advantage, in particular turbulent flows and particle-image velocimetry (PIV). Experience with laser-based and other optical methods is highly relevant. However, extensive laboratory experience with other state-of-the-art lab techniques can in some cases compensate.
• Previous knowledge of turbulence and/or surface waves is an advantage.
• Experience with building and developing laboratory set-ups is particularly valuable.
• Experience with writing or developing code and methods for data analysis is particularly valuable.
• A background in curiosity-driven fundamental research is preferred over applied/industrial engineering research.

Female applicants are particularly encouraged (or other non-male gender).

NOTE: a background in computational fluid mechanics with standard software (e.g. ANSYS, OpenFOAM) is not particularly relevant and does not itself qualify for the position.

Personal characteristics

• enthusiastic and driven
• efficient while diligent
• inventive, able to find creative solutions to problems
• a team player and generous collaborator
• tolerant and flexible in a highly diverse environment

Emphasis will be placed on personal and interpersonal qualities. Due to the extended responsibilities within the research group, statements from references will be important, and the interview stage will be done carefully, possibly involving two rounds of interviews depending on the applicants.

Salary and conditions

As a Postdoctoral Fellow (code 1352) you are normally paid from gross NOK 573 900 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund

The period of employment is 4 years.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants  (in Norwegian), and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criteria in the latter law will be prohibited from recruitment to NTNU.  

After the appointment you must assume that there may be changes in the area of work.

The position is subject to external funding from the European Union.

It is a prerequisite you can be present at and accessible to the institution on a daily basis.

About the application

The application and supporting documentation to be used as the basis for the assessment must be in English.

Publications and other scientific work must accompany the application. Please note that your application will be considered based solely on information submitted by the application deadline. You must therefore ensure that your application clearly demonstrates how your skills and experience fulfil the criteria specified above. 

If, for any reason, you have taken a career break or have had an atypical career and wish to disclose this in your application, the selection committee will take this into account, recognizing that the quantity of your research may be reduced as a result. 

The application must include:

• CV and certificates
• transcripts and diplomas for bachelor’s-, master’s- and PhD degrees
  • in English; provide an official/professional translation if necessary.
  • If you have not yet completed your Ph.D, you must provide confirmation on your estimated date for the doctoral dissertation, or that your PhD thesis has been submitted
  • for transcripts from countries outside Norway, please include an official explanation of grades for international comparison (often provided by the awarding University).
• Academic works – published or unpublished – that you would like to be particularly considered in the assessment (up to 5 items)
• Research plan, maximum 1 page (see below)
• Name and contact information of three references

The research plan should outline a 4-year experimental project to study the fluid mechanics of the upper ocean. Clearly, applicants will have differing degrees of knowledge, which will be taken into account. The plan need not conform with the actual project but should show an understanding of planning and executing a laboratory campaign to study WTC properties in a lab where waves, turbulence and currents can each be tailored individually, from first steps to publishable data representations.

If all, or parts, of your education has been taken abroad, we also ask you to attach documentation of the scope and quality of your entire education. Description of the documentation required can be found here . If you already have a statement from NOKUT, please attach this as well.

Joint works will be considered. If it is difficult to identify your contribution to joint works, you must attach a brief description of your participation. 

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal and interpersonal qualities. Motivation, ambitions, and potential will also count in the assessment of the candidates. 

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment – DORA.
