Daniel Fröhlich studied Chemistry at the Johannes Gutenberg University Mainz from 2003-2008. He completed both his diploma thesis (2008) and his PhD (2009-2011) at the Institute of Nuclear Chemistry in the group of Prof. Dr. Tobias Reich. During his research he focused on the speciation of neptunium during migration in natural clay. Since 2012 he works as a Post-Doc at the Institute of Physical Chemistry at the Ruprecht Karls University of Heidelberg in the group of Prof. Dr. Petra Panak. There he deals with the thermodynamics of complex formation reactions of trivalent actinides with organic and inorganic ligands in aqueous solution at elevated temperatures. The used analytical methods especially include the time-resolved laser fluorescence spectroscopy (TRLFS) and extended x-ray absorption fine structure spectroscopy (EXAFS).

 

Daniel Fröhlich studierte von 2003-2008 im Diplomstudiengang Chemie an der Johannes Gutenberg Universität Mainz. Er fertigte sowohl seine Diplomarbeit (2008) als auch seine Dissertation (2009-2011) am Institut für Kernchemie in der Arbeitsgruppe von Prof. Dr. Tobias Reich an und beschäftigte sich im Rahmen seiner Forschungsarbeiten mit der Speziation von Neptunium bei der Migration in natürlichem Tongestein. Seit 2012 ist er als wissenschaftlicher Mitarbeiter am Physikalisch-Chemischen Institut der Ruprecht Karls Universität Heidelberg in der Arbeitsgruppe von Prof. Dr. Petra Panak tätig. Dort beschäftigt er sich mit der Thermodynamik von Komplexbildungsreaktionen dreiwertiger Actiniden mit organischen und anorganischen Liganden in wässriger Lösung bei erhöhten Temperaturen. Die Analysenmethoden umfassen vorallem die zeitaufgelöste Laserfluoreszenzspektroskopie (TRLFS) und die Röntgenabsorptions-Feinstrukturanalyse (EXAFS-Spektroskopie).
