He has worked on most of the electrode materials (both positive and negative), for supercapacitors as well as Lithium and Sodium-ion batteries, from synthesis to materials characterization. He completed is PhD in 2001 and worked as a postdoctoral fellow at the University of Waterloo (Canada) and ICMCB (Bordeaux, France). He joined the University of Nantes as a faculty member in 2007 His research focuses on new materials for aqueous electrochemical capacitors, with a special attention to device design. He co-authored more than 30 papers for the last ten years.
