Frank Breher performed his Ph.D. studies at the Universities of Oldenburg and Marburg (10.1998 to 03.2001) under the supervision of Prof. W. Uhl. He spent his postdoctoral period in the research group of Prof. H. Grützmacher at the ETH Zürich, Switzerland (DFG fellowship), where he became an independent researcher in 2002 supported by a Liebig fellowship. In 2005 he accepted a faculty position at the Universität Karlsruhe (TH) and became Assistant Professor in January 2006. Subsequently, he was promoted to W3-Professor for Inorganic Chemistry at the Karlsruhe Institute of Technology (KIT) in April 2010. His research interests centre around the synthesis, structure, bonding and reactivity of organometallic and coordination compounds of unusual Main Group element cages/clusters and transition metal complexes. Spectroscopic techniques including cyclic voltammetry, EPR spectroscopy, and advanced NMR methods as well as density functional theory calculations are also of interest. In 2016, he was awarded the faculty teaching award. From 10.2016 to 09.2021, he was Dean of Study Affairs (Chemistry).

Alexander Hinz obtained his Diplom under the supervision of Prof. Martin Köckerling at the University of Rostock with studies of transition-metal-containing ionic liquids in 2012. For his doctoral studies, he joined the group of Prof. Axel Schulz at the same university and explored new group 15 singlet biradicaloids and their reactivity. In 2015, he seized the opportunity to join Prof. Jose Goicoechea’s group at the University of Oxford as a post-doctoral researcher, where he investigated the chemistry of heavy analogues of the cyanate anion. Since April 2018, he has been recipient of a Liebig Fellowship of the Fonds der Chemischen Industrie and, afterwards, obtained an Emmy-Noether fellowship of the German Science Foundation. He is developing sterically highly demanding substituents for the stabilisation of terminal main-group and transition-metal nitrides as well as low-coordinate main-group species.
