Biography

Urban studied physics at the University of Stuttgart and was awarded a PhD in 1972 for his dissertation on the study of the damage caused by the electron beams in a high-voltage electron microscope at low temperatures. He subsequently conducted research at the Max Planck Institute of Metals Research in Stuttgart until 1986. Amongst other tasks, he was involved in the installation of a 1.2-MV high-voltage microscope laboratory as well as in studies on the anisotropy of atomic displacement energy in crystals and on radiation-induced diffusion. In 1986 he was appointed professor of general material properties by the Department of Materials Science and Engineering at the University of Erlangen-Nuremberg. In 1987 Urban was appointed to the chair of experimental physics at RWTH Aachen University and simultaneously became the director of the Institute of Microstructure Research at Forschungszentrum Jülich. From 1996 to 1997 he was a visiting professor at the Institute for Advanced Materials Processing of Tohoku University in Sendai (Japan). Kurt Urban was appointed one of two directors of the Ernst Ruska Centre for Microscopy and Spectroscopy with Electrons (ER-C) when it was founded in 2004 as a common competence platform of Forschungszentrum Jülich and RWTH Aachen University as well as a national centre for users of high-resolution transmission electron

Research Intrest

High-resolution transmission electron microscopy, electro ceramics, quasicrystals and intermetallic phases.
