Postdoctoral Fellow

Your tasks

You contribute to implementing optimal data acquisition and processing procedures to achieve high-resolution ptychographic image reconstruction for the characterisation of metal oxide electrocatalysts and biological macromolecules. Within a collaboration with colleagues at the Swiss Light Source SLS, you will analyse the obtained data and help to fine tune the processing algorithms along with data acquisition settings to obtain best results from materials science and biological samples. You will be presenting the work at international conferences and in peer-reviewed scientific journals.

Your profile

  • University degree with PhD level in physics, chemistry, materials science, or natural sciences
  • Hands-on experience in electron microscopy (TEM and STEM)
  • Strong communication and collaboration skills in an international environment
  • Experience in 4D STEM methods is a strong plus • Experience in programming and/or image processing
  • Fluent communication in English
This job is for you if:
  • You are interested in electron ptychography and motivated by developing new methods in electron microscopy
  • You enjoy both, experimental electron microscopy and data analysis, and are familiar with real and reciprocal space
  • You feel comfortable in an interdisciplinary team
  • It is beneficial if you have experience with analysis of large datasets and image processing algorithms used in low dose electron microscopy
