Joachim Ullrich (physicist)

from Wikipedia, the free encyclopedia

Joachim Hermann Ullrich (born June 2, 1956 in Edenkoben ) is a German physicist and university professor . Ullrich has been President of the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig since January 1, 2012 .


Ullrich studied Geophysics and Physics at the University of Frankfurt , where, after graduating in 1983 and 1987, Horst Schmidt-Böcking doctorate and over 1,994 recoil ion momentum spectroscopy (RIMS) habilitation . After working for the Society for Heavy Ion Research (1989 to 1994), he went to Kansas State University in Manhattan as a visiting scientist and visiting professor at the University of Missouri in Rolla in 1995 . In 1997 he accepted a full professorship at the Albert Ludwig University of Freiburg . In 2001 he moved to the Max Planck Institute for Nuclear Physics in Heidelberg as Director and Scientific Member and has also been an honorary professor at the Ruprecht Karls University of Heidelberg since 2002, and since 2003 he has also been a Consultant Professor at the Fudan University in Shanghai .

Ullrich works in the fields of atomic physics , spectroscopy and laser physics as well as molecular physics . The main focus of his work lies in the field of experimental many-body quantum dynamics.
