Stéphane Torelli received his Ph.D. in Chemistry from the University Joseph Fourier (Grenoble, France) in 2000, under the supervision of Prof. J.-L. Pierre and Dr. C. Belle, working in the field of bio-inspired chemistry. He then joined the group of Prof. L. Que Jr. at the University of Minnesota (USA) as a postdoctoral fellow (2000–2001), where he developed iron complexes as models of mono- and dinuclear non-heme iron enzyme active sites. From 2001 to 2002, he was appointed Associate Lecturer at the University of Grenoble (Department of Chemistry), focusing on bio-inspired models of blue and red copper enzymes. From 2002 to 2004, he worked at the University of Geneva (Switzerland) with Prof. C. Piguet, investigating light-induced energy transfer processes in heterodinuclear Ru–Ln helicates and novel Ln-based metallomesogens. In 2004, he was appointed CNRS researcher at the University Grenoble Alpes. Between 2004 and 2008, his work in the Department of Chemistry centered on the development of new iron complexes to study various aspects of iron metabolism in marine bacteria. In 2009, he joined the Laboratory of Metals in Biology (BioCE team, CEA Grenoble) to initiate research on the (i) reactivity of sulfur-containing dinuclear copper complexes as functional models of copper metalloenzymes involved in N₂O and, more recently, O₂ reduction and (ii) photocatalytic substrates oxidation mediates by Ru-Cu dyads. In 2025, he joined the SolHyCat team to further develop his projects towards materials-oriented and applied research, still in the field of small molecules (O2, CO2…) activation/transformation.
