PHD BSC (NANCY, FRANCE)

Biography

From 2005-2008 Pierre completed his Ph.D. in Theoretical and Computational Chemistry at the University of Nancy, France under the supervision of Prof. Xavier Assfeld, his dissertation was awarded the best PhD in Molecular Physics and Chemistry. In 2008-2012 he was awarded an ARC Fellowship for post doctoral studies at the Research School of Chemistry, ANU under Professor Peter Gill. More recently in 2012 Pierre was awarded an ARC Discovery Early Career Researcher Award.
