Do you want to contribute to a more sustainable future and development of solutions for the circular economy? The Farm Technology Group at Wageningen University & Research is offering a 4-year PhD position to work on the development and assessment of new and rapid analyses and test procedures of bio-based fertilisers, commencing 1 Sept 2020. The work of the PhD fellow will be part of the EU FertiCycle Network, which is a multidisciplinary European Training Network (ETN) funded by the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie actions. The Ferticycle Network comprises 9 world leading universities and 7 research institutions / agencies/companies in 8 European countries. The FertiCycle Network is currently recruiting 15 highly talented and motivated candidates for PhD studies, with the skills, knowledge and enthusiasm to help our network make successful research breakthroughs on new bio-based fertilisers from organic waste upcycling – the chosen candidate will be collaborating with these colleagues for the coming 4 years. Are your interested to read more about the other projects? You can find them on the project website:

The candidate will work with bio-based fertilizers and develop the techniques for rapid analysis of the contents. The PhD candidate will develop a protocol for rapid analysis and test of bio-based fertilisers with near infra-red (NIR) spectroscopy, GC-MS, FTIR-PAS and to analyse a wide range of bio-fertilisers via the aforementioned and conventional methods. The developed methods will be validated through comparison of results with conventional chemical methods and the next goal will be to optimize the process.

The candidate will therefore focus on spectral data acquisition and processing. The objective will be to develop innovative methods for rapid analysis and characterization of various contents in bio-based fertilizers. The developed techniques should be robust and able to be deployed in real-world conditions. Once the protocol for characterization of materials through spectroscopy is established, the next task will be to extend the method for hyperspectral imaging. The challenges of low light levels, changing illuminations and pre-processing of hyperspectral data will be addressed. The result should be a protocol of image acquisition and analysis for rapid and accurate analysis of contents in the bio-based fertilizers. New and innovative techniques to improve the spectral analysis should be developed
in this project. The identification of most relevant spectral bands across hyperspectral imaging will lead towards the development of specialized multispectral cameras. The availability of these imaging systems and data processing techniques for obtaining the information about contents of bio-based fertilizers.

In this position you will closely work together with Dr. Haris Ahmad Khan and Prof. Dr. Peter Groot Koerkamp. Dr. Eric Meers from University of Gent, and Dr. Sander Brunn from University of Copenhagen will be the co-supervisors.


We ask

  • MSc degree in Computer Vision, Optics, Image Processing or similar.
  • Experience with spectral image acquisition and processing.
  • Good skills in data management and analysis.
  • A team player who can work independently and who also communicates well with colleagues;
  • excellent written and oral communication skills in English.
  • Affinity with chemical methods and analytical chemistry will be an advantage.
  • Knowledge of computational imaging and colour constancy techniques will be an advantage.
  • Experience with cross-disciplinary and/or multi-cultural collaboration will be an advantage.
  • For admission to the graduate school PERC of Wageningen University, your MSc degree should be equivalent to a Dutch MSc degree.
  • If the candidate is from a non-Anglophone country and has not completed the higher education with English as the language of instruction, an internationally recognised Certificate of Proficiency in the English Language should be submitted. Minimum required scores:
    • TOEFL internet-based 90, with minimum sub-score 23 for speaking
    • IELTS 6.5, with minimum sub-score 6.0 for speaking
    • Cambridge Certificate of Advanced English (CAE) with minimum grade B
    • Cambridge Certificate of Proficiency in English (CPE) any grade
  • Test results must be dated within 24 months prior to the application.
In order for applicants to be eligible for this position, they have to fulfil certain criteria:
H2020 MSCA Mobility Rule: applicants must not have resided or carried out their main activity (work, studies, etc.) in the country of the host organisation (in this case Netherlands) for more than 12 months in the 3 years immediately before the recruitment date (start of contract). Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status are not taken into account.

H2020 MSCA eligibility criteria: Early Stage Researchers (ESRs) must be, at the date of recruitment by the host organisation, in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. Full-Time Equivalent Research Experience is measured from the date when the researcher obtained the degree entitling him/her to embark on a doctorate (either in the country in which the degree was obtained or in the country in which the researcher is recruited, even if a doctorate was never started or envisaged).

We offer

In principle this is a 48-month PhD position. We offer you a temporary contract for 12 months which will be extended with three years if you perform well. Gross salary per month: € 2325,-  based on full time employment. You will be appointed as PhD according the Dutch collective university rules. On top of that you will receive a travel and, if applicable, a family allowance.

In addition, we offer:

  • 8% holiday allowance;
  • a structural end-of-year bonus of 8.3%;
  • excellent training opportunities and secondary employment conditions;
  • flexible working hours and holidays can possibly be figured out in consultation so that an optimal balance between work and private life is possible;
  • excellent pension plan through ABP;
  • 232 vacation hours per year, plus the option to purchase extra and good supplementary leave schemes;
  • a flexible working time: the possibility to work a maximum of 2 hours per week extra and thereby to build up extra leave;
  • a choice model to put together part of your employment conditions yourself, such as a bicycle plan;
  • a lively workplace where you can easily make contacts and where many activities take place on the Wageningen Campus. A place where education, research and business are represented;
  • use the sports facilities on campus.
Wageningen University & Research stimulates internal career opportunities and mobility with an internal recruitment policy. There are ample opportunities for own initiative in a learning environment. We offer a versatile job in an international environment with varied activities in a pleasant and open working atmosphere.
