    Full Time

The Department of Electrical and Computer Engineering, Aarhus University, Denmark invites applications for a 3-year postdoc position in the field of signal processing, machine learning and instrumentation. The position is anchored in a new research project, SuperTEM, where novel instruments for groundwater mapping based on transient electromagnetics (TEM) are developed.

Expected start date and duration of employment
This is a 3-year position available from August 15th, 2021 or as soon possible.

Project description
Groundwater is an integral part of satisfying global water needs. Yet, proactive management practices must be implemented to ensure long-term sustainable use of groundwater resources, as overexploitation can quickly deplete groundwater reserves

A key component of informed management practices is data on available resources. Such data can be obtained with the use of non-invasive, high-resolution electric and electromagnetic geophysical exploration techniques. Transient electromagnetics (TEM) is particularly adept at rapid cost-efficient mapping of groundwater systems.

In a new project, we are exploring two new TEM-based exploration methods. The first is a permanently installed, monitoring TEM instrument capable of tracking changes in groundwater levels. The instrument is designed for long-term deployment with autonomous operation and data-streaming to remote servers.  The second method is a semi-airborne TEM designed for high-resolution 3D mapping. This instrument combines a ground-based transmitter with a roving drone-carried receiver.

The postdoc will be contribute to the research and development of both new instruments.

  • You will be doing research, development, and implementation of novel signal processing and machine-learning algorithms related to the operation of the monitoring instruments. You will also participate in programming of instrument control and communication software, and will participate in instrument development, testing and field validation.
  • You will investigate the electromagnetic and vibrational noise induced in TEM data by the drone, and will be doing research, development, and implementation of new signal-processing or machine-learning workflows to mitigate such noise. You will be involved in programming of instrument control software as well as testing and field validation.

You will work closely with the other members of the research group and the external partners in the project.  We therefore expect that you have strong communication and collaboration skills and are prepared to work in interdisciplinary research setting. The research is expected to lead to several journal papers and we therefore expected good dissemination skills documented through a strong publication track record.  As a postdoc, you will have the opportunity to contribute to other on-going research projects in the group as well as opportunities to contribute to supervision of Masters and PhD students.

The postdoctoral fellowship is funded by Innovation Fund Denmark. There is funding for 3 years of employment. For international applicants, Aarhus University offer help with relocation, housing and formalities.

Required qualifications for the position:

  • PhD degree in electrical engineering, physics, geophysics or similar
  • Experience with signal processing and machine learning
  • Experience with instrumentation development
  • Programming experience
  • Strong analytical skills
  • Experience with transient electromagnetics or other geophysical methods is an advantage, but not required
  • Excellent English skills, both oral and in writing
  • A desire to work in an interdisciplinary research project

Who we are
About the Department of Electrical and Computer Engineering. Electrical and computer engineering are closely related engineering disciplines that focus on the development of hardware and software for intelligent units and networks.

The Geophysics, instrumentation, and signal processing group,,  currently consists of one Associate Professor, three postdocs and one PhD student. On this project, we are working closely together with the large Hydrogeophysics Group at the Department of Geoscience,

What we offer

  • a well-developed research infrastructure, laboratories and access to state-of-the-art equipment
  • an exciting interdisciplinary environment with many national, international and industrial collaborators
  • a research climate encouraging lively, open and critical discussion
  • a work environment with close working relationships, networking and social activities

Place of work and area of employment
The place of work is Finlandsgade 22, 8200 Aarhus N, Denmark, and the area of employment is Aarhus University with related departments.

Application procedure
Shortlisting is used. This means that after the deadline for applications – and with the assistance from the assessment committee chairman, and the appointment committee if necessary, – the head of department selects the candidates to be evaluated. All applicants will be notified whether or not their applications have been sent to an expert assessment committee for evaluation. The selected applicants will be informed about the composition of the committee, and each applicant is given the opportunity to comment on the part of the assessment that concerns him/her self. Once the recruitment process is completed a final letter of rejection is sent to the deselected applicants.

Letter of reference
If you want a referee to upload a letter of reference on your behalf, please state the referee’s contact information when you submit your application. We strongly recommend that you make an agreement with the person in question before you enter the referee’s contact information, and that you ensure that the referee has enough time to write the letter of reference before the application deadline.
Unfortunately, it is not possible to ensure that letters of reference received after the application deadline will be taken into consideration.

Formalities and salary range
Technical Sciences refers to the Ministerial Order on the Appointment of Academic Staff at Danish Universities under the Danish Ministry of Science, Technology and Innovation.

The application must be in English and include a curriculum vitae, degree certificate, a complete list of publications, a statement of future research plans and information about research activities, teaching portfolio and verified information on previous teaching experience (if any). Guidelines for applicants can be found here.

Appointment shall be in accordance with the collective labour agreement between the Danish Ministry of Finance and the Danish Confederation of Professional Associations. Further information on qualification requirements and job content may be found in the Memorandum on Job Structure for Academic Staff at Danish Universities.

Salary depends on seniority as agreed between the Danish Ministry of Finance and the Confederation of Professional Associations.

Aarhus University’s ambition is to be an attractive and inspiring workplace for all and to foster a culture in which each individual has opportunities to thrive, achieve and develop. We view equality and diversity as assets, and we welcome all applicants.

Research activities will be evaluated in relation to actual research time. Thus, we encourage applicants to specify periods of leave without research activities, in order to be able to subtract these periods from the span of the scientific career during the evaluation of scientific productivity.

Aarhus University offers a broad variety of services for international researchers and accompanying families, including relocation service and career counselling to expat partners. Read more here. Please find more information about entering and working in Denmark here.

Aarhus University also offers a Junior Researcher Development Programme targeted at career development for postdocs at AU. You can read more about it here.

The application must be submitted via Aarhus University’s recruitment system, which can be accessed under the job advertisement on Aarhus University's website.
