Biography

Yann Leroux is a 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 on 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. 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).
