I am interested in understanding the forces which hold atomic nuclei together, in particular the role played by meson exchange currents and nucleon-nucleon correlations. I am also interested in the properties of hadrons and nucleon resonances which can give an insight into the internal structure of the particles which make up the bulk of the known mass of the universe. My research uses real and virtual photons to probe the forces between nucleons. I carry out most of my work using the Glasgow tagged photon facility at the Mainz 1.6 GeV electron microtron (MAMI) in Germany and in the CLAS collaboration at Jefferson Lab in the United States. I have a smaller involvement in programmes at other labs.
