Prof Robinson's interest are in X-ray diffraction using synchrotron radiation, for which he developed the methods for studying surface structure based on crystal truncation rods, which he discovered and built them into a definitive technique for the determination of the atomic positions at surfaces and interfaces.
Since coming to UCL, he has been developing coherence-based methods for use at the latest synchrotron sources to enable direct 3D imaging of structure on an ultrafast time scale; once coupled with Bragg diffraction, this is a powerful way to examine strain distributions and domain formation inside complex crystalline materials.
