The Plant Sciences Division of the Institute of Bio- and Geosciences (IBG) investigates the dynamics of plant processes and the interaction of plants with the environment. Plant science at Forschungszentrum Jülich plays a leading role at national and international level in the field of plant phenotyping, i.e. in the quantitative and non-invasive recording of structural and functional properties of plants important for agricultural and horticultural plant breeding. In this context, IBG-2 together with three breeding companies has initiated the project "Shape & Color", which aims at the use of non-invasive or partly-invasive methods as well as new algorithmic approaches for the quantitative characterization of plant properties in vegetable and herbal breeding processes for selected plant species.

We are offering a

PhD position – Non-invasive methods for the quantification of plant properties relevant for horticultural plant breeding

Your Job:

  • Development and implementation of new phenotyping platforms for the acquisition of image and spectral data in selected plant species of all involved breeding companies
  • Development of new/revision of available algorithms for quantitative characterization of plant properties from digital imaging and spectral measurements. The focus is on quality traits like shape and color features of selected crops
  • Rating of different methodic approaches via the breeding evaluation scales
  • Optional: Development of workflows for image processing and data analysis for routine operation in the breeding process

Your Profile:

  • Completed master degree in computer science, image processing or a comparable subject area with interest in plant science topics
  • Alternatively: Completed master degree in natural, engineering or agricultural science or a comparable subject area with good background in digital image processing
  • Experience with image analysis and feature acquisition from RGB images; ideally experience in analyzing spectral data
  • Ideally, experience with programming languages and software that are used for image processing, e.g. C++, Python, OpenCV, Matlab etc.
  • Practical experience with optical sensors and their components such as cameras, spectroscopic measurement systems and illumination
  • A high degree of initiative, responsibility and team spirit
  • You are fluent in German and have a very good command of the English language

Our Offer:

  • Working at one of the largest and best-known European research facilities with excellent scientific and technical infrastructure
  • Opportunity to work in a team of highly-motivated scientists and technicians in an international, interdisciplinary working environment on an attractive research campus, ideally situated between the cities of Cologne, Düsseldorf, and Aachen
  • Promotion of professional development through participation in national and international conferences and further development of your personal strengths via various training programs
  • Continuous technical support via a team of supervisors
  • The contract is limited for 3 years
  • Pay in line with 50 % of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund).


Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women.

We also welcome applications from disabled persons.
