The Ernst Ruska-Centre (ER-C) for Microscopy and Spectroscopy with Electrons at Forschungszentrum Jülich is a national facility dedicated to research at the frontiers of electron microscopy. It is part of a multilateral interdisciplinary initiative of 7 Helmholtz Centres dedicated to pushing the limits of ptychography, which a computational method to reconstruct microscopic objects. As a member of the moreSTEM research group lead by Prof. Dr. Knut Müller-Caspary, your research contributes state-of-the art electron microscopy experiments and methodology to the consortium of mathematicians, X-ray scientists and IT experts dealing with Big Data challenges.

We are looking to recruit a

PhD position - Advanced electron ptychography for materials and life sciences

Your Job:

  • Perform experiments with state-of-the-art aberration-corrected low-voltage STEM machines equipped with ultrafast cameras to record 4D STEM data of 2D materials and biological as well as soft matter specimen
  • Automate multidimensional data acquisition and evaluation is to a high level
  • Implement and test novel ptychographic reconstruction schemes in close cooperation with mathematicians, X-ray scientists and IT experts
  • Acompanying simulations to validate results, to optimise acquisition and reconstruction parameters and to frame ranges of validity of ptychographic schemes in electron microscopy
  • Play a key role in the methodological development of momentum-resolved STEM techniques

Your Profile:

  • Master`s degree in physics
  • A background and strong interest in scattering theory, solid state physics and/or experiences in electron microscopy are desirable
  • Programming experience in, e.g., Matlab, Python
  • Experience in the field of structural biology/biophysics is beneficial.
  • Fluent command of written and spoken English
  • Most importantly: enthusiam to explore uncharted territory, develop and follow your own ideas
  • Ability to work autonomously in close interaction within a team

Our Offer:

  • Oustanding computing facilities and partly unique aberration-corrected transmission electron microscopes equipped with ultrafast detectors of the latest generation
  • A highly motivated working group as part of an international and interdisciplinary working environment at one of Europe’s largest research establishments
  • Continuous scientific mentoring by your scientific advisor as well as feedback and expertise in the multiple facets of electron microscopy, materials science and structural biology
  • Opportunity of participating in (international) conferences and project meetings
  • Participation in overarching seminars including certificate.
  • Further development of your personal strengths, e.g. via a comprehensive further training programme
  • Pay in line with 50 % of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund), higher payment may be possible upon skills
  • Information on employment as a PhD student at Forschungszentrum Jülich can be found here
  • Usually a contract for the duration of 3 years
