Yann LEROUX (35 years old) is a young physical-chemist, specialized in electrochemistry and surface sciences. He obtained his PhD from the University of Paris VII – Denis Diderot, Paris, France, in 2007 under the supervision of Pr. Jean-Christophe Lacroix. During this time, he focused his researches in the design and realization of active plasmonic devices and electrochemically generated atomic contacts. He obtained the 2008 PhD Thesis Prize from the Division de Chimie-Physique de la Société Chimique de France. (One of his researches has resulted of a highlight in Nature journal). Between 2008 and 2009, he held a post-doctoral position in the group of Pr. Marcel Mayor in Basel, Switzerland, one of the world leaders in molecular electronics. Since 2009, he is now a CNRS researcher, in the group of Dr. Philippe Hapiot in Rennes, France. His main research activities are the surface modification and characterization by localized electrochemical methods. He is currently looking for self-organized molecular architecture using aryl diazonium chemistry, along with the development of Scanning Electrochemical Microscopy (SECM).

His activity has led to the publication 34 peer-review international research papers (h-factor: 15, 672 citations), 2 peer-review national research papers, 1 book chapter and 13 oral communications in international conferences and 2 invited seminars in national and foreign universities. He supervised 3 PhD students and 9 undergrad students during the last five years. He received in 2012 the International Society of Electrochemistry travel award for young electrochemist.
