Joachim Ullrich (physicist)

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 .

Life

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.

Awards and other offices

• Ullrich was awarded the Gottfried Wilhelm Leibniz Prize of the German Research Foundation in 1999.
• In 2004 he was awarded the David Bates Medal by the London Institute of Physics .
• In 2006, together with Robert Moshammer, he received the Philip Morris Research Prize for the development of the reaction microscope, a combined electron-recoil ion spectrometer, with which few-particle processes (e.g. collisions of electrons with ions, chemical reactions or the electron emissions after laser excitation of atoms ) in atomic and molecular physics can be observed more precisely than before in terms of their kinematics. The device is an analogue in atomic physics to the bubble chamber in elementary particle physics. The end products are directed to large-area detectors by means of electric and magnetic fields. They built on a development initiated by Ullrich's doctoral supervisor Horst Schmidt-Böcking .
• Ullrich has been a member of the American Physical Society since 2007 . In 2008 he was named a "Fellow" by her.
• In 2010 he was awarded the Silver Badge of Honor from the German Electron Synchrotron Research Center.
• As President of the Physikalisch-Technische Bundesanstalt, he has been Chairman of the Board of Trustees of the Werner-von-Siemens-Ring Foundation and Chairman of the Board of Directors of the Helmholtz Fund since 2012.
• In 2013, Ullrich was elected as a second deputy in the Presidium of the German Institute for Standardization and a member of the German Academy of Engineering Sciences .
• As part of the Meter Convention , Ullrich also became a member of the International Committee for Weights and Measures (CIPM), whose “Consultative Committee for Units” (CCU) he has been President since the beginning of 2014.
• In 2015 he was elected to the Berlin-Brandenburg Academy of Sciences .
• 2017 Federal Cross of Merit 1st class
• 2018 honorary doctorate from Gottfried Wilhelm Leibniz University Hannover
