Introduction
Dr. Mickaël CASTRO is currently lecturer at University of South Brittany, France since 2009. He obtained his PhD from the University of Saint-Etienne in 2004, studying the morphology and the rheological behaviour of co-continuous immiscible polymer blends. During his post-doctorate at the University of Minnesota, he studied the rheology of concentrated surfactant systems. He joined the Materials Engineering Laboratory of Brittany in the Smart Plastics Group in 2006 to develop self-sensing conductive polymer composites.
