Bernhard Keimer's research addresses central and complex aspects of solid state physics. An outstanding international expert on neutron diffraction, Keimer's name is tied closely to the innovative research methods he has pioneered in his twenty-year-long quest to understand high temperature superconductivity in cuprates – a group of chemical compounds containing copper anion. In his ground-breaking research Keimer uses inelastic neutron diffraction to study spin excitation in high temperature superconductors. The basis of these neutron experiments is a programme initiated by Keimer for the production of purpose-built single crystals to be assembled in mosaics of several hundred minute and near-perfect samples. In his studies of other structures, such as the magnetic structure of ruthenate-cuprate compounds, Keimer adopted the same long-term strategy. In other research Keimer has contributed significantly to our understanding of Mott insulators.

Shortly after completing his pre-diploma in physics, Bernhard Keimer transferred to the world-renowned Massachusetts Institute of Technology (MIT) in Boston, where he also completed his doctorate. Keimer subsequently held a number of professorships in Princeton before he was appointed Director of the Max Planck Institute for Solid State Research in Stuttgart in 1999. He is one of the most frequently cited scientists in his field worldwide, associate editor of several leading professional journals, and a member of numerous academies. Widely respected as an academic mentor, Keimer has attracted early career researchers from around the world to the institute in Stuttgart.
