Research Interests


  • Hadronic Physics - I am interested in investigating the properties of hadrons using a variety of theoretical tools.

  • Lattice QCD - Currently I am working with Jo Dudek and Robert Edwards in the Hadron Spectrum Collaboration. We have been investigating meson-meson scattering to better understand the excited states in the hadron spectrum, see for example: arXiv:1406.4158 and arXiv:1411.2004.

  • I am interested in Nucleon form factors and have worked on these using the Dyson-Schwinger equations, Bethe-Salpeter equation and Faddeev equation frameworks that use non-perturbative methods to understand the inner workings of QCD interactions. These can be used to obtain form factors particularly relevant to Jefferson Lab physics, see for example: arXiv:1112.2212.

  • I am also interested in the non-perturbative dressing of the fields of the Lagrangian of QCD, including the Gluon propagator, see for example: arXiv:1109.2117.
