Dr. Antoine le Duigou is Associate-Professor in Institut de Recherche Dupuy de Lome at Université de Bretagne Sud (Lorient France).

Antoine obtained his PhD in Materials Science at Université de Bretagne Sud and Ifremer in 2010, under the supervision of Pr C Baley P Davies where he developed natural fibre biocomposites for marine application. In 2014, he introduced the novel concept of Hygromorph biocomposites. Natural fibres’ main drawback, i.e moisture sensitivity, is for the first time turned into an advantage thanks to biomimicry paradigm. A new functionnality for natural fibres was proposed. He won Young’s researcher award from French Composites Association (AMAC) in 2017 and from European Society of Composite Materials (ESCM) in 2018. He defended his Habilitation in 2017 dealing with Composites materials and natural fibres : From reinforcement to hygromorph actuators . He has published more than 65 internationally peer reviewed articles and has given more than 80 conferences.

From a pedagogical and administrative point of view, Antoine is in charge of the Master 1 “Eco-Design of Polymers and Composites”.

Dr. Mickaël CASTRO is currently a lecturer at the University of Southern Brittany, France, since 2009. He obtained his PhD at the University of Saint-Etienne in 2004, studying the morphology and rheological behavior of co-continuous immiscible polymer blends for lithium battery applications. During his post-doctoral fellowship at the University of Minnesota, he studied the rheology of concentrated surfactant systems, under the supervision of Pr. C.W. Macosko. He joined the Materials Engineering Laboratory of Brittany in the Smart Plastics group in 2006 to develop self-sensing conductive polymer composites as part of a European project under the supervision of Pr. J-F. Feller. In recent years, efforts have mainly focused on the integration of conductive composite sensors in composite structures, for monitoring the health of composites structural parts (SHM). The work on the monitoring of structural parts and the submission of a patent are at the origin of the creation of a startup (Sense in).

Finally, more recently and following internal collaborations, he has collaborated in the development of functional biocomposites for applications of hygromorphic passive actuators, and have participated for example in the addition of conductive formulations in these systems to monitor and/or modify the kinetics of their response. From a pedagogical and administrative point of view, Mickael is in charge of the Master 2 “Eco-Design of Polymers and Composites”, and of a University diploma entitled “3D Printing: Innovative Composite Materials”. He is elected to the operating council of his Sciences faculty, and also to the Research Commission of the University of Southern Brittany.
