He conducted Polylactide (Ingeotm) technology development and engineering scale-up studies for Cargill/NatureWorks  – 150 kton production facility for PLA, the world’s foremost 100% biobased and biodegradable-compostable polymer material. He engineered advanced PLA-biopolyester hybrid resin materials that is commercial (www.natur-tec.com). He developed starch biofoam materials for cushion protection and insulation packaging. He is actively researching biodegradability and compostability studies of polymer plastics and engineering flow composter systems for managed end-of-life of compostable plastics with biodegradable organic wastes.

Dr Nathanaël GUIGO - ICN

"Enjeux et perspectives associés aux chaines de valeur des polymères furaniques biosourcés"

Nathanael Guigo is associate professor at Université Côte d’Azur. He is specialized in physical chemistry of polymers with a peculiar interest on sustainable polymeric materials following a circular approach (e.g. valorization of co-products from biorefineries or industry). His scientific expertise relies to the structure/property relations in polymers such as re-organization during processing/recycling, comprehensive understanding of cross-linking, glass transition behaviour, crystallization, thermal degradation. His research interests are particularly focused on biobased furanic polymers - both thermoplastics (e.g. PEF) and thermosets (humins resins, furanic epoxies, etc.). He is co-author of more than 75 publications (ORCID 0000-0002-0858-4093).
From 2010, he has been actively involved as PI and co-I of several national (ANR JCJC FUTURES) and EU projects (BIOFUR in FP7; ITN project HUGS in H2020). N. Guigo is currently the Vice-Chair of the European COST Action FUR4SUSTAIN (CA18220) dedicated to the furandicarboxylic acid (FDCA) chain value.

Dr Emilie VERNEUIL - SIMM

"Interactions polymères/substrat et frottement"

Emilie Verneuil est chercheur au CNRS au sein du laboratoire SIMM (Sciences et ingénierie de la Matière Molle) / ESPCI Paris, dans l'équipe Matière Molle Hors d'Equilibre. Sa recherche porte sur la dynamique des interfaces dans des liquides complexes (solutions de polymères ou tensioactifs, gels, fondus de polymères). Les problèmes qu'elle aborde sont souvent inspirés de problématiques appliquées liées aux procédés industriels (filtration d’émulsions ou suspensions, dépôt de revêtements, ou dissolution de poudres...) qui soulèvent des questions fondamentales de mouillage, frottement, ou de transport. Sur la base d'expériences originales, son approche vise à décrire les couplages entre les contraintes et les transferts de matière aux interfaces et en volume, en combinant des aspects de mécanique et hydrodynamique avec la physico-chimie et la thermodynamique.

Pr Julien GAUTROT - QMU

"Polymer brush design for gene delivery - Macromolecular architecture and biomolecular interactions"

Julien Gautrot is Professor in Biomaterials and Biointerfaces in the School of Engineering and Materials Science and Engineering at Queen Mary, University of London. His research focuses on the development of biointerfaces and microengineered biomaterials for stem cell technologies and the design of advanced cell culture platforms. In particular, his group has explored the physico-chemical properties of polymer brushes, the regulation of interactions of biomacromolecules at these interfaces and pioneered their application for the design of stem cell microarrays and for gene delivery. He has published over 90 research articles, including in journals such as Chem. Rev., Nat. Mater., Nat. Cell Biol., Nat. Commun., Angew. Chem. Int. Ed., ACS Nano, Advanced Functional Materials and Nano Letters. In 2017, he was awarded an ERC consolidator grant to explore the design of bioemulsions for stem cell technologies. Since 2021, he is Director of the CDT in Molecular Biochemical Engineering at QMUL.

Pr Christophe CHASSENIEUX - LMU

"Micelles inanimées, avez-vous donc une âme qui s’attache à notre âme et la force d’aimer ?"

Christophe Chassenieux est Professeur des Universités au sein de l’Institut des Molécules et des Matériaux du Mans à l’Université du Mans depuis 2005 après avoir été Maitre de Conférences à Jussieu pendant 7 ans. Il est physicochimiste de la matière molle (colloïdes, émulsions, hydrogels). Il cherche à contrôler la structure et la dynamique d’auto-assemblages de polymères en variant la nature des interactions entre différents types d’ingrédients (polymères amphiphiles, polysaccharides, protéines, tensioactifs, colloïdes (in)organiques,…). Parmi ses travaux, on peut citer ceux sur des assemblages à l’équilibre thermodynamique de polymères amphiphiles à blocs conduisant à des hydrogels de dynamique contrôlée, ceux sur les séparations de phase liq/liq conduisant à la formation d’émulsions eau dans eau et de microcapsules protéiques et enfin ceux sur la gélification de suspensions denses. Depuis, plus récemment, il s’intéresse au vieillissement de micro- et nanoparticules de plastiques en milieux aqueux.
