Julien

Julien studied chemistry at the University of Lausanne, Switzerland, and graduated with a Diplôme de chimiste in 2001 working under Carlo Floriani on the synthesis of coordination compounds reactive to dinitrogen. He then joined Dan Nocera's group at the Massachusetts Institute of Technology in the USA to prepare and investigate novel molecules able to store electrons at both a transition metal ion and an organic site. After obtaining his Ph. D. in inorganic chemistry from MIT in 2006, Julien moved with a Humboldt Fellowship to the department led by Ulrich Gösele at the Max Planck Institute of Microstructure Physics in Germany to learn the chemistry and physics of solids. He worked as a postdoc at the University of Hamburg with Kornelius Nielsch for two years, and obtained a junior faculty position in physics in Hamburg in October 2009. Julien is  also recognized as a faculty member in the chemistry department. In his research, Julien applies chemical concepts and methods to the preparation of novel nanostructured materials with well-controlled physical properties.

Julien is now an associate professor of inorganic chemistry at the Friedrich Alexander University of Erlangen-Nürnberg.
