PhD opportunity in diffractive imaging: ptychography - a form of atomic scale lensless imaging

This is an opportunity to make a key contribution to one of the most advanced imaging technologies currently being developed for ultra-high resolution imaging using X-rays and electrons. The method (called ‘ptychography’ in the scientific literature), originally developed by Professor Rodenburg, makes images without using good-quality lenses, but instead processes diffraction patterns. By no longer needing good lenses, which are very hard to make at sub-atomic wavelengths, ptychography has revolutionised X-ray microscopy: part of the aim of this post is to make similar transformational paradigm change in electron imaging and/or biological cell imaging.

Depending on your background, the project can be weighted towards either experimental or theoretical (and/or modelling) work.

The studentship will cover full PhD tuition fees and a tax-free stipend. This is also true for EU citizens who have been resident in the UK for at least three years. Non-resident EU students are not eligible for the stipend. There may be an opportunity to have a partial fee-waiver awarded for a very well qualified non-EU candidate. Candidates with their own funding are also encouraged to apply. The studentship can start at the earliest opportunity.


  1. Applicants should have, or expect to obtain, a first-class or good 2:1 honours degree, or a distinction or high merit at MSc level (or international equivalent) in physics, electronics and/or electrical engineering, or a similar physical science or engineering subject.
  2. Applicants should preferably be able to demonstrate an interest in optics and/or inverse problems.
  3. Previous experience with MATLAB is desirable; computing experience with a scientific programming language is essential.
