Bernhard Keimer (born 24. August 1964 in Ratingen) is a German physicist and Director at the Max Planck Institute for Solid State Research. His research group uses spectroscopic methods to explore quantum many-body phenomena in correlated-electron materials and metal-oxide heterostructures.

Life

Keimer obtained his physics education at the Technical University of Munich and at the Massachusetts Institute of Technology, where he received his Ph.D. degree in 1991. He spent a year as postdoctoral associate at Massachusetts Institute of Technology and seven years on the faculty of Princeton University, where he was appointed Full Professor in 1997. In 1998 he was appointed Scientific Member of the Max Planck Society[1] and Director at the Max Planck Institute for Solid State Research.[2] In 2000 he was named Honorary Professor at the University of Stuttgart. He serves as Speaker of the International Max Planck Research School for Condensed Matter Science and Co-Director of the Max Planck Society – University of British Columbia Center for Quantum Materials.
