Gérard Cahiez received his Ph.D. in 1973, at the University Pierre & Marie Curie (Paris VI) under the supervision of Professor Jean-François Normant on the carbocupration of terminal alkynes (vinyl copper reagents).
Then, he joined the CNRS.
After a post-doctoral year in the Roussel Uclaf Laboratories (now Sanofi) working on the chemistry of steroids, he came back to the University Pierre and Marie Curie and, in 1980, he became Director of Research at the CNRS.
Then, he moved to the Ecole Supérieure de Chimie Organique et Minérale (ESCOM, Cergy-Pontoise) in 1993. From 1993 to 2008 he was Director of Research at the CNRS and professor of chemistry at ESCOM.
From 2000 to 2009, he was also director of the UMR 8123, a joint research unit CNRS–University of Cergy Pontoise–ESCOM.
In 2009, he moved to the University of Paris 13, as Director of Research at the CNRS.
Then, in 2013, he moved his research group to the IRCP (Research Institute of Chimie Paris) at Chimie ParisTech (ENSCP).
The research developed since 1973 has dealt with the use of organometallic reagents in organic synthesis and especially with the development of the chemistry of organomanganese reagents.
His current interest is still focused on organomanganese chemistry but more generally on the search for new highly selective organometallic reactions, i.e., Mn-, Co-, and Fe-catalyzed cross-coupling reactions, involving non toxic and inexpensive metals or additives.
