Stéphane Le Gac completed his PhD in organic chemistry in 2006 under the supervision of Prof. I. Jabin, at the University of Le Havre, where he developed molecular receptors derived from calix[6]arenes. He started a first postdoctoral period at the Free University of Brussels (Belgium) with Prof. A. Kirsch-De Mesmaeker, working with ruthenium-oligonucleotide photo-reagents for skin cancer therapy. He then moved to the Radboud University in Nijmegen (The Netherlands) as a postdoctoral fellow in the groups of Prof. R. Nolte and Prof. A. Rowan, aiming at the development of new strategies for the functionalization of helical polymers (polyisocyanides). In 2009, he was appointed CNRS researcher at the University of Rennes (France) where he obtained his Habilitation diploma in 2014. His current research interests lie in the field of porphyrinoids: supramolecular coordination chemistry, bimetallic complexes, molecular switches, (anti)aromaticity control, Möbius twisted receptors.
