Geraint is a Postgraduate Researcher in the School of Mathematical Science at the University of Southampton. He is part of the Applied Mathematics and Theoretical Physics group.

His research concerns the phases of matter under extreme conditions, extreme enough to compete with the strong force. This force is responsible for keeping protons and neutrons in the nucleus and the quarks that make up those protons and neutrons confined. At such high energies, it is necessary to describe matter in terms of subatomic particles like quarks and pions. Specifically, he works in the limit of extremely high magnetic field, comparable to those found in neutron stars and heavy-ion collisions. By varying the magnetic field, this quark or nuclear matter can undergo phase transitions in a similar way to how everyday objects can transition between solids, liquids and gases by changing the temperature. Of particualr interest are superconducting phases. Superconductivity is a phase which is sensitive to changes in the applied magnetic field, where the internal magnetic field is either expelled completely(type-I) or confined to flux tubes within the interior(type-II).
