Sven Kullander is a professor of High Energy Physics at Uppsala University. He has been involved in measurements of nuclear shell structure using a beam of protons to knock out bound protons from atomic nuclei, in the study of the form and the structure of the helium nucleus using high energy p-meson scattering, in investigations of the elementary hadron-nucleon scattering amplitude at very high energies using small-angle hadron-hydrogen elastic scattering, in the elucidation of quark structure of matter based on high-energy muon-nucleus scattering and in experiments on the production of light mesons near their kinematical thresholds in proton-hydrogen scattering. In his research he has used synchrocyclotrons, synchrotrons and cooler storage rings. He has also contributed to the development of accelerators and new instrumentation and measurement methods.
