Jean-Cyrille Hierso was born in Toulouse (France) in 1971. He studied physical chemistry at the Université Paul Sabatier (UPS Toulouse), working on palladium nanochemistry (MsD 1994, Laboratoire de Chimie de Coordination du CNRS) and on organometallic chemical vapor deposition of group 10 transition metal complexes (PhD 1997, UPS-Ecole Nationale Supérieure de Chimie de Toulouse). After postdoctoral works on pyrazolylborate group 5 organometallics (LCC-CNRS), and then on cobalt oximes coordination chemistry (Leiden Institute of Chemistry-CBAC, Netherlands), he has been appointed Assistant Professor at the University of Burgundy in 2001. He has been promoted Associate Professor in 2006 (Habilitation), and Full Professor in 2009 at the Institute of Molecular Chemistry of the University of Dijon, working on ligand design, palladium and copper homogeneous and heterogeneous catalysis, NMR spectroscopy and organometallic chemistry for sustainable development. He has co-authored about 50 papers and reviews in the fields of chemical vapor deposition, transition metals organometallic and coordination chemistry (Pd, Pt, Ni, Rh, Cu, Ta, Zr, Co, Mn) hetero- and homogeneous catalysis, metallo-ligand organic synthesis, C–C bond formation (Heck, Suzuki, Sonogashira reactions) and physical chemistry for NMR studies.
