I am an associate professor at the Sorbonne Université, leading the Materials & Biology team at the Condensed Matter Chemistry Laboratory of Paris (LCMCP).
His current research interests span the large field of biomaterials with a particular focus on the integration of biological functions in exogenous materials. The main strategy is to adapt materials science processing techniques to meet the requirements of living matter.
I have obtained a degree in Chemistry and a MSci in Environmental Sciences from the University of Minho in Braga, Portugal. I’ve then moved to Madrid, Spain to pursue a PhD under Prof. Ruiz-Hitzky guidance at the Materials Science Institute of Madrid, focusing on the interface between biopolymers and clay minerals to develop bionanocomposite materials. In 2011, I moved to Paris to integrate the LCMCP as a post-doctoral fellow working on collagen-based materials for biomedical applications.

In multicellular organisms, tissues are structured as complex—often hierarchical—assemblies of biopolymers and living cells. The ability to reproduce the features of the native architecture of such biopolymer systems (the extracellular matrix, ECM) opens exciting perspectives in designing new, more relevant materials for 3D cell culture.
Using type I collagen, the main component of mammals’ ECM we have recently shown that freezing under carefully controlled conditions allows to design macroporous materials that can host primary cells in a 3D environment for extended periods of time.
Ice templating (or directional freezing, freeze casting, etc…) allows for controlled phase separation events during freezing. We have shown that when controlled freezing is applied to biopolymer solutions with cells in suspension, it allows for the encapsulation of cells withing the biopolymer matrix.
These results shine a new light on cell cryopreservation, the single available technique to extend the lifespan of biological entities. Systematically used from research labs up to the clinic, cell cryopreservations relies on toxic cryoprotectants (such as DMSO or glycerol) to minimize the deletrious effects induced by ice crystals on living cells. Applying new strategies to control the freezing events (such as directional freezing) opens new avenues to maximise cell viability in absence of toxic cryoprotectants
Designing cell-containing materials is critical for a wide range of applications. From soil biodegradation to wound healing or bone regeneration, we rely heavily on the work provided by cellular entities.
One of our main research lines aims at designing radical new approaches to build cell-containing materials. Our efforts in rationalizing the spatial relations between cells and their host materials during fabrication have led to a double criteria that determines the possible cellularization pathways—fabrication process cytocompatibility and porosity.
