    Academic projects

    3D printing of biobased polymer aerogels for biomedical applications (October 2019 - September 2022)
    The objective of this project is the 3D printing of bio-aerogels and evaluation of their use as drug-releasing wound dressings. The project is at the interface of materials science (biobased polymers, aerogels, 3D printing), chemistry (polymer functionalization) and biomedical applications (wound dressings, controlled release).
    This highly interdisciplinary project will be carried out in collaboration with the Institute of Biomolecules Max Mousseron (IBMM), Montpellier, which has extensive experience in the domain of medical devices and controlled release systems.

    Oligosaccharidic (multi)block copolymers with tunable composition (November 2017 - October 2021)
    The main objective of the project is to widen the possibilities of creating new chemical structures from oligosaccharide blocks by preparing and studying the properties of a new class of (multi)block copolymers based exclusively on the assembly of oligosaccharides bearing different properties. After preparation and thorough characterization, the structure of these block copolymers is related with their physical, physico-chemical and mechanical properties. Collaborations with Université de Picardie et Université de Lyon.

    Industrial projects

    Starch porous materials for controlled delivery (started February 2019)
    The objective is to prepare, characterize and understand if and how porous materials from starch can be used as delivery matrices.

    Biomass For the Future (November 2014 - October 2021)
    BFF aims at the development of cropping systems and new varieties of sorghum and miscanthus as well as new markets: energy (heat and methane), polymer composites for the automotive industry and load bearing miscanthus concrete blocks for construction. One of the objectives is to define the optimal combination of raw materials / valorisation thanks to the association of specialists in plant biology, ecophysiology, genomics, material science, life cycle analysis, agronomists, breeders, farmers and process engineers.
