This is how Queen's University and its surrounds look through the seasons: Autumn, Winter (atypical), Spring

You can find Queen's at the bottom of the Belfast City Centre map.

My research interests are mainly in Theoretical Atomic Physics, and I do my research in the Centre for Theoretical Atomic, Molecular and Optical Physics (CTAMOP).

- Many-body theory in atoms.
- Electron-atom scattering, negative ions, photodetachment.
- Interaction of positrons with atoms and molecules: scattering, bound states and annihilation.
- Quantum chaos in complex atoms and other many-body systems.
- Multiphoton processes in strong laser fields.
- Cold atom scattering.

Still at school and thinking about doing a Mathematics or Applied Mathematics and/or Theoretical Physics degree? These are all largely about problem solving, and here is a selection of some of my favourite simple and not so simple maths problems.
