Postdoctoral Researcher – Computational Electron Microscopy and M...

• Conducting research at the interface of electron microscopy and machine learning, including the application and adaptation of established methods, data analysis, and dissemination of results
• Identifying open questions in electron microscopy where progress is limited by analysis rather than by instrumentation, and where new machine learning methods therefore offer genuine scientific gain
• Developing, training and evaluating deep learning models for microscopy data – real-space imaging, 4D-STEM diffraction and in-situ time series – including the construction and characterisation of the experimental and simulated datasets your research requires
• Establishing what physically meaningful evaluation means for such models: what constitutes a correct answer, when an output is an artefact of the measurement, and which failure modes matter for the underlying materials science
• Conducting and interpreting simulation studies (e.g. multislice, Bloch-wave methods) that connect experiment, theory and model behaviour
• Participation in the scientific agenda of our collaboration with the ER-C: bringing microscopy questions into our method development, and turning model results into statements that are meaningful to microscopists
• Publishing in microscopy and materials science journals as well as at machine learning venues, and contributing to open datasets, benchmarks and software
• Co-supervising doctoral and master students, and contributing to proposal writing and to the group’s third-party funded projects

## Your Profile

We are looking for a highly motivated colleague who is excited about new scientific endeavors with interdisciplinary approaches. For this you have:

• Completed Master's degree and PhD in Physics, Materials Science or a closely related field
• In-depth working knowledge of electron microscopy, including image formation and contrast mechanisms, electron diffraction, and substantial experience in at least one of the following: 4D-STEM, in-situ or operando microscopy, or quantitative HR(S)TEM.
• Experience with electron microscopy simulations (e.g. multislice or Bloch-wave methods), or with developing quantitative data analysis pipelines for microscopy data, which would be a strong asset.
• Practical, hands-on experience in training deep learning models, solid programming skills in Python, and working proficiency with PyTorch or an equivalent framework.
• A clear interest in developing methods rather than merely applying them, as well as the motivation to substantially deepen your machine learning expertise within the group.
• Excellent communication skills across disciplinary boundaries; much of the value of this role lies in enabling two research communities to understand one another.
• Strong analytical skills, creativity
• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the [CEFR](https://go.fzj.de/languagerequirements)), ideally supported by a certificate confirming the language level
