Quantum electrodynamics (QED) is the remarkably successful theory of the interaction of light and matter. It shows unprecedented levels of agreement with experiment, with the most famous example being the anomalous magnetic moment of the electron, where theory and experiment have found consistency up to one part in 10 trillion. In order to design the next generation of precision tests of QED, the effect the extended material objects have on the fundamental properties of atoms and electrons in their vicinity must be quantified to ever-increasing precision, since the experimental apparatus is inevitably make up of such objects. The main part of the talk will be an outline of one of these effects, namely the surface-dependent shift in the anomalous magnetic moment of an electron [1,2]. Following this there will be a brief presentation of some newer work concerning atomic level shifts and decay rates near complex nanostructures [3], as well as an account of a recently-developed unified approach to Casimir forces for fields carrying arbitrary spin [4,5] in which the electromagnetic Casimir force emerges as a special case.
