PhD position - Advanced electron ptychography for materials and life sciences

As a member of the Helmholtz Association, Forschungszentrum Jülich makes an effective contribution to solving major challenges facing society in the fields of information, energy, and bioeconomy. It focuses on varied tasks in the area of research management and utilizes large, often unique, scientific infrastructure. Come and work with around 6,100 colleagues across a range of topics and disciplines at one of Europe's largest research centres.

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.

Activities and responsibilities

  • 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

Qualification 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

We 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
