Doctoral researcher (m/f/d) MarDATA-4 Real-time Signal Processing

Deadline: July 04, 2021

GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation of public law jointly financed by the Federal Republic of Germany (90 %) and the state of Schleswig-Holstein (10 %) and is one of the internationally leading institutions in the field of marine sciences. Currently GEOMAR disposes over an annual budget of approx. 80 million Euro and has approx. 1.000 employees.

The research unit Deep Sea Monitoring of the research division Marine Geosystems is offering a position as

Doctoral researcher (m/f/d) MarDATA-4 in Computer Science and Marine Data Science with Focus on Real-time Signal Processing for the Hydroacoustic Detection and Classification of Underwater Objects

starting on September 1st, 2021. The position offers the possibility to attain a doctoral degree in engineering.

The doctoral research project within the framework of the “Helmholtz School of Marine Data Science” (MarDATA). MarDATA is a graduate school, financed by the Helmholtz Association. It aims to define and educate a new type of “marine data scientists” by introducing and embedding researchers from computer sciences and mathematics into ocean sciences, covering a broad range from supercomputing and modelling, (bio)informatics, robotics, to statistics and big data methodologies. Education of doctoral researchers in joint block courses, international summer schools and colloquia goes beyond a single discipline towards genuine scientific insight into and a more systematic treatment of marine data.

Job Description

The main research questions are in the area of cognitive multi-input-multi-output (MIMO) SONAR systems. The project will investigate improvements in the detection of backscattering objects (e.g., rising gas bubbles or schools of fish) underwater, considering the scarce resources in autonomous vehicles. Also, optimal parameter selection will be ensured by using machine learning approaches (reinforcement learning).


  • Prerequisite is a university degree (master's or diploma) in electrical engineering and information technology, physics, computer science or a related field of study completed with high honors
  • Solid knowledge of digital signal processing is required
  • Pattern recognition skills are necessary
  • Programming skills in either C/C++, MATLAB and/or Python are required
  • Experience with SONAR/RADAR procedures and how they work are helpful
  • Knowledge of AUVs is beneficial, but not a prerequisite
  • Knowledge of the use of hydroacoustic methods in maritime sciences is helpful
  • Enjoy learning other fields of research
  • Teamwork and flexibility to be part of two groups
  • Very good English skills are a prerequisite

If the required degree is not completed at the time of application, the degree certificate must be handed in before the above start date of the contract and the application must contain plausible evidence that the degree can be finished before that date.

We offer:

  • Work at the Faculty of Engineering at CAU and at GEOMAR (Signal Processing Working Groups at CAU and DeepSea Monitoring at GEOMAR)
  • Use of technology in the field
  • Testing developments in applied geoscientific projects
  • International colleagues
  • Friendly and supporting work environment

The position is available for a funding period of 3 years. The salary depends on qualification and could be up to the class 13 TVöD-Bund of the German tariff for public employees. This is a full-time position. The position cannot be split. Flexible working time models are generally possible. The fixed-term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).
