Stéphane Torelli studied chemistry at the University Grenoble Alpes where he defended his Ph.D. in 2000 in the field of copper chemistry regarding synthetic models of catechol oxidases under Pr J. L. Pierre and Dr. C. Belle. As a postdoc fellow at the chemistry department at the University of Minnesota he developed iron systems for modelling mono and dinuclear non-heme iron active sites under Pr. L. Que, Jr (2000-2001). From 2001 to 2002 he was appointed associated teacher at the University Grenoble, department of chemistry (DCM) where he prepared sulfur-containing ligand and related copper complexes to approach the redox singularity of blue copper enzymes. He then joined the goup of Pr C. Piguet for a postdoctoral fellowship at the University of Geneva (2002-2004, department of inorganic chemistry) where he synthesized and studied light-induced energy transfer processes in hetero-dinuclear Ru-Ln helicates and independently developed new types of Ln-based metallomesogens. After that, he achieved an appointment as CNRS researcher at the University Grenoble Alpes in 2004 to elaborate new iron complexes to study various aspects of iron metabolism in marine bacteria. Finally, in 2009, he joined the Laboratory of Metals in Biology on a new topic dealing with the preparation, characterization and reactivity studies of sulfur-containing dinuclear copper complexes for modelling the nitrous oxide reductase metalloenzyme (N2O ® N2 + H2O) and more recently O2 activation for selective H2O2 production.
