Prof. Dr. Joachim H. Ullrich

Joachim Ullrich, born in 1956, studied geophysics and physics at the University of Frankfurt where, after graduating in 1983, he also completed his doctorate in 1987 and qualified as a professor in 1994. From 1989 to 1997 he worked as a research assistant at the Gesellschaft für Schwerionenforschung in Darmstadt, where he played a key role in further developing recoil ion spectroscopy. After a research period at Kansas State University and a visiting professorship at the University of Missouri in 1995, he received a call to the chair of experimental physics at the University of Freiburg in 1997. With his appointment as a director of the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, he headed the department “Experimental Multiparticle Quantum Dynamics" from 2001. Since the beginning of 2012, Joachim Ullrich has been President of the Physikalisch-Technische Bundesanstalt.


Joachim Ullrich has received wide recognition at national and international level for his scientific work, which encompasses approximately 600 publications. Among other honors he has received the Leibniz Prize of the German Research Foundation in 1999. He is active in the committees of many international conferences, scientific advisory boards and supervisory boards. In 2013, Joachim Ullrich became second deputy of the Presidial Board of the German Institute for Standardization e. V. and a member of Germany’s National Academy of Engineering Sciences (acatech). For the Meter Convention, Joachim Ullrich has been a member of the International Committee for Weights and Measures (CIPM), Vice President of the CIPM since 2015 and, since the beginning of 2014, President of the Consultative Committee for the International Units (CCU). As a world-renowned researcher and science manager, Joachim Ullrich received the Federal Cross of Merit 1st Class of the Federal Republic of Germany in 2017.
