• Simulation of certain aspects of these experiments
• Quantification and correction of systematic errors
• Presentation of results within collaborations and at international conferences
• Teaching

Your profile:

• We are seeking applicants with an PhD in astronomy/astrophysics and expertise in some of the varied and important skill sets required for the cosmological lensing analysis of Rubin/LSST and Euclid. These skills include:
  • image processing,
  • image simulation,
  • photometry,
  • shear and redshift estimation,
  • mock catalogue production,
  • statistical data analysis,
  • cosmological parameter inference and
  • theoretical modelling of weak lensing observables.
• Letters of recommendation from two referees should be sent to [e-mail] before the closing date.
• Candidates should submit a CV and research proposal of up to two pages each via RUB’s BITE application system before Jan 5th 2026.
