Guy Denuault undertook his undergraduate training at the Reims Institute of Technology where he received his first degree and subsequently at Bordeaux University where he received his Master’s degree. He joined the Southampton Electrochemistry Group and carried out experimental and theoretical investigations into the application of ultramicroelectrodes in mechanistic and kinetic studies of coupled chemical reactions. He received his Ph.D. in 1989 and moved to the University of Texas at Austin where, in the group of Allen Bard, he worked on the development of the scanning electrochemical microscope (SECM). He returned to Southampton and took up a 5-year EPSRC Advanced Research Fellowship to continue the development of the SECM technique. He was appointed Lecturer (1993), Senior Lecturer (2000), and Associate Professor (2014).
He was visiting professor at the University of São Paolo (1998), University of Bordeaux (1999), National Polytechnic Institute of Grenoble (2006) and University of Oldenburg (2011-2012). In 2011, he became a Fellow of the Hanse Institute for Advanced Study. His research has led him to deliver postgraduate courses overseas (Bern, Buenos Aires, Geneva, Grenoble, Lausanne, Neuchatel, São Paulo) and to present invited research seminars in the UK and abroad (Bordeaux, Buenos Aires, Campinas, Grenoble, Lausanne, Limerick, Nancy, Oldenburg, Ribeirãon Preto, Rio Cuarto, Rio De Janeiro, Riyadh, San Carlos, São Paulo, Singapore, Venice, Warnemünde).
