More information


Our Guest Researcher Programme originated when PTB researchers expressed interest in inviting their peers from other metrology organisations.

Acting on their wish, we set up the PTB Guest Researcher Programme, whose aim is to facilitate collaboration between metrologists from all over the world.

Guest researcher stays at PTB are designed to yield new and deeper scientific insight into current metrology issues or a new or improved national standard or method.

Working temporarily at PTB can entail many advantages for you:

  • It will provide you with a platform to learn and develop as a metrologist and may boost your career
  • You will work on a challenging and exciting project at a renowned NMI
  • Contact to your international peers often lasts a lifetime
  • Your home institution will benefit from your research results as well as from a good relationship with your host at PTB
  • You will have the opportunity to learn more about Germany
  • You will gain both professional and intercultural experience


Eligibility and sponsoring

PTB’s Guest Researcher Programme is open to scientists and engineers from NMIs* and DIs** or from other scientific or technological institutions working in the area of metrology, e.g. universities.

A guest researcher must be an employee of one of the institution types listed above. The home institution must be willing to continue paying the researcher’s salary during their stay at PTB.
