Dr Serge Cosnier is currently Research Director at CNRS and director of the Department of Molecular Chemistry (that employs 140 people and comprises five research teams and eight scientific platforms) at the Grenoble Alpes University (France) where he began his research career in 1983. He received his doctoral degree in Chemistry from the Toulouse University (1982) and was an Alexander von Humbold postdoctoral fellow at the Ludwig Maximilian University of Munich, Germany. From 2001 to 2014, he was the President of the French Group of Bioelectrochemistry and was President of the Rhône-Alpes section of the Chemical Society of France (2007-2013). He has worked extensively in the dissemination and strengthening of bioelectrochemistry in France. To this end, he was heavily invested nationally in the direction of two CNRS GDR networks "Microbiosensors" (2003-2010) and "Enzymatic and Microbial Biofuel cells" (2012-2015). At the international level, he was the coordinator of a France-China CNRS network (GDRI, 20 laboratories) on "New approaches for water control and sustainable energy by electrochemical biosensors and biofuel cells” (2009-2012) and a CNRS France-Israel program (PICS) "Inhibitors of communication between bacteria" (2014-2016). He is also editor, associate editors or member of the editorial board of several journals: Frontiers in Analytical Chemistry, Current Analytical Chemistry, Frontiers in Bioenergy and Biofuel, Electroanalysis, Talanta, Current Organic Synthesis, SRX Chemistry, The Open Current Process Chemistry Journal and The Open Analytical Chemistry Journal. Dr Cosnier’s activity is focused on the molecular electrochemistry and bioelectrochemistry with the development of electrode materials whose applications include analytical chemistry with biological sensors (enzyme electrodes, immunosensors, aptasensors and DNA sensors), electrocatalysis, photochemistry, bioreactors and electrochemical biomimetic systems, energy conversion (hydrogen ⇔ electricity), biofuel cells and abiotic fuel cells. He has developed innovative conceptual advances in the field of conducting polymers, and inorganic nanostructured materials (TiO2, synthetic redox clays, CaCO3 nanoparticles and bismuth oxide). More recently he has conceived new 3D nanostructured electrode materials based on functionalized carbon nanotubes intercalated with nano-objects like graphene, magnetic nanoparticles, gold nanoparticles or nanodiamonds. He also developed electrogenerated polymers covering the field of organometallic films, biofilms and films with photoactivable, chiral or fluorescent properties applied to bioelectrochemistry. He has designed various strategies of protein immobilization on these polymers by photochemical grafting, host-guest interactions or affinity interactions. Dr Cosnier has made extensive fundamental and applied contributions to the field of transduction of biological recognition processes by electrochemical methods (amperometry, impedance, electrochemiluminescence, photocurrents). Dr Cosnier has authored over 367 peer reviewed publications (h-index 64), 3 books and 18 book chapters, and holds 19 patents. In 2009, he received the Katsumi Niki Prize of the International Society of Electrochemistry and was appointed as Fellow of this Society in 2010. In 2013, Dr Cosnier became a member of the Academia Europaea and was nominated as a Finalist for the European Inventor Award 2014 by the European Patent Office. In 2015, he was awarded Doctor Honoris Causa of the University of Medicine and Pharmacy of Cluj-Napoca (Romania), received the Grand Prix Joseph-Achille Le Bel : Prize awarded by the Chemical Society of France and was nominated Knight of the National Order of the Legion of Honor (France). He received also in 2015 an Award of the Chinese Academy of Sciences : CAS President’s international fellowship initiative to distinguished scientists. In 2016, he was nominated Doctor Honoris Causa of the Polytechnic University of Bucharest (Romania) and was the recipient of the 2016 China-France Chemistry Award from the Chinese Chemical Society and the Chemical Society of France. Finally, he was elected member of the European Academy of Sciences (EurASc) in 2019 and was the recipient in 2018 of the Costin D. Nenitescu Medal awarded by the Romanian Chemical Society.
