Research interests

I work in the field of hadron spectroscopy which can be understood using Quantum Chromodynamics (QCD), part of the Standard Model of Particle Physics. QCD is a strongly-coupled field theory at the energies where hadrons arise, meaning that perturbation does not apply, posing a significant calculational challenge. One method which has shown great promise in recent years is Lattice QCD, where the quantum fluctuations in a finite volume are sampled numerically using Monte-Carlo methods, to extract finite volume spectra. Using a mapping originally derived by Lüscher and extended by many others, these finite volume energy levels can be used to constrain infinite volume hadron scattering amplitudes. My current research is on numerical extractions of coupled-channel scattering amplitudes, which are in turn used to understand hadron resonances as poles in the complex energy plane.
