Job Title

Postdoc Machine Learning Development of Machine Learning Architectures for Data Evaluation

Job Description

New membranes for the separation of substances are being developed with experiments and simulations at the Institute of Membrane Research. In past years, the evaluation of large experimental datasets by means of machine learning has become increasingly important. Within the project COMPUTING, we aim to uncover correlations between parameters and structures that remain hidden in individual experiments in order to advance the understanding of processing-structure-property-relationships of polymer membranes. For this, we will establish machine-learning-based data evaluation methods for large sets of microscopic images and fabrication parameters. Developing novel machine learning architectures and modifying published methods will be a key task in this position. The project is a collaborative effort with the Institute of Material Systems Modelling at Hereon and the HIP Service Unit ‘Applied Computer Vision Lab’ at DKFZ.

We are looking for a data scientist, computer scientist, physicist or engineer with a PhD degree as soon as possible. This position is initially limited to 21 months due to the project’s funding, with a high chance for extension in further projects. The place of work is the Helmholtz-Zentrum Hereon in Geesthacht. Part of the work can be conducted via home office.

Equality of opportunity is an important part of our personnel policy. We would therefore strongly encourage qualified women to apply for the position.

  • experience in statistical methods and methods of data science
  • background in object-oriented programming preferable
  • fluency in spoken and written English
  • experience with scientific methods, project planning, publications and presentations
  • German language skills are an advantage

Your personal profile
• systematic and goal-oriented way of working
• sense of responsibility and a high demand for quality in your work
• ability to tackle complex problems and to think outside the box
• joy of working in a small team and flexibility regarding the tasks involved
• proactive communication skills
• openness to an international and dynamic working environment in science
• willingness to familiarize yourself with new topics, e.g. polymer chemistry and membrane technology
