Educations and experiences

Researchgate profile

With a chemical engineering background I started in 2010 a PhD in physical-chemistry on the syntheses and characterizations of nanoparticles for biomedical applications. While going deeper into my nanoparticles skills I learned new knowledge on toxicities and biological behaviors of nanohybrids made for medical purposes.

During my postdoctoral experiences from 2011 to 2016, in particular at EPFL, I continued working on synthesis and characterizations methods "GMP-like" for nanomaterials in order to answer pharmaceutical and medical requirements. I also focused my research on the study and the understanding of the role of nanoobjects physico-chemistry on the living world especially their interactions with protein from biological media: the "Protein Corona"

This thematic is driving my actual research at ICB Laboratory (Nanosciences Department).

2007-2010: After a chemical engineering diploma from the University of Technology of Compiegne (UTC), I started a PhD in physical chemistry at the ICB Laboratory on the Elaboration of functionalized nanoparticles: applications as MRI contrast agent. My research was focused on the syntheses of magnetic nanparticles via soft chemistry or hydrothermal and continuous methods with an accurate control of the physicochemical properties and in depth characterizations. Nanoparticles' surfaces were also modified and functionalized for a better biocompatibility, less toxicity and targeting behviors in order to be used as a Magnetic Resonance Imaging (MRI) contrast agent.

2011-2015: I worked for 4 years in Pr. H. Hofmann's team at the Ecole Polytechnique Fédérale de Lausanne (EPFL) on a FP7 European project (Nanodiara) on the development of novel nanotechnology based diagnostic and therapeutic systems for arthritic diseases. My research was centered on one part on the reproducibility and scale-up of the syntheses and methods to face biomedical challenges. On another part, I studied the interactions between nanoparticles and proteins in order to better understand their biological behaviors. This scientific area is commonly called: the "Protein Corona".

2015-2016: After these projects, I continued my research at Dublin City University (Pr. Dermot Brougham) on a FP7 European project (UNION). Then at Basel University (Pr. Cornelia Palivan) I worked on a Swiss project NCCR (National Centres of Competence in Research). These two projects were focused on the development of physicochemical solutions for biomedical applications such as  "nano-flowers" or "nano-vesicles".

Since the end of 2016: I got a CNRS Researcher (CR) permanent position at the Nanosciences Department of the ICB laboratory to continue working on my thematic focused on  the development of nanomedical solutions and on the understanding of their biological behaviors.

Main projects in progress

2021-2026: ANR JC/JC Nanoblorona
Nanoparticles in blood: understanding and controlling protein corona for optimized nanomedicine

Role during the project: Project leader.

The main goal of this project is to understand, control and optimize protein corona on NPs to avoid suffering random protein adsorption affecting the biomedical efficiencies of engineered NPs circulating in blood.

This project proposes a comprehensive study focused on NPs/proteins interactions in blood circulation in order to control their biological response.

2021-2024: ANR UFO
Up-conversion ferroelectric nanocrystal for optical sensing for electric potential in biological systems

Role during the project: Member of WP3 (Project leader F. Treussart ENS Paris-Saclay)

Developing an optical nanosensor of extracellular potential in biological environment that transduces cell-related electrical changes (e.g. EAP in the case of neurons) into photoluminescence (PL) modifications relying on a mechanism never explored.

2020-2022: Collaborative Research Project France-Stanford
Monitoring therapeutic cell treatments using novel nanoprobes.
Role during the project: Project leader.

Tissue regeneration through transplantation of therapeutic stem cells has the potential to revolutionize modern medicine by migrating and differentiating to integrate into their biological environment. We propose to test innovative nanomaterials, which possess unique properties that make them detectable simultaneously by two medical imaging techniques to label stem cells and monitor the efficacy of therapeutic stem cells. Visits and collaborations with Stanford Medicine: Pr. Daldrup-Link Lab.

2019-2022: Regional project on the studies and understanding of proteins interactions with NPs' surfaces (Inititation of a new research team ANER: Nanoprot” n° 2019-Y-10648)

Role during the project: Project leader.

This project focuses on the in depth study and understanding of the parameters influencing the adsorption of proteins on the surface of nanoparticles of various parameters (surface chemistry, charges, shape, size...). The idea is also to understand how this protein corona influences chemical, colloidal and biological behaviors of nanoparticles. This project is mainly done by the PhD student Célia Marets and in collaborations with University of Geneva.

Description du projet:

Project description:

This NCCR project was pooling multidisciplinary areas from the physics and chemistry to the biology, the biostatistics and the computer sciences.

The main objctive of the "Molecular Systems Engineering" project was to create complex molecular layouts to mimic cellular reactions. Such systems can be use as organic molecules (enzymes for example) industrial productions or to control cellular systemps for applications in health.

2011-2014: FP7 European project (Nanodiara)
Development of nanotechnological tools for the detection and the therapy of arthrtic diseases.
Role during the project: Co-project leader of WP1

Project description:

Although treatment of rheumatoid arthritis (RA) has improved in the last years, there is still no disease modifying treatment for osteoarthritis (OA). For treatments to be effective it is considered extremely important to detect and treat these diseases early and then be able to monitor treatment efficacy early on (within weeks or months) after its initiation rather than waiting up to a year for RA and 18 months for OA. RA is a chronic inflammatory joint disease that involves acute and chronic synovial (joint lining) inflammation causing the erosive destruction of articular cartilages, ligaments and subchondral bone. It develops in about 1% of the population. OA, currently the main cause of disability among the middle age and elderly populations, is a degenerative arthritis involving much less synovial inflammation in most patients, with a prevalence of about 12% of the population.

Role during the project:

As a scientist and WP leader at EPFL, my role was pivotal and consisted in bringing nanotechnological solutions to our biological, industrial and medical partners. As main responsibles of the WP 1, we worked in close collaborations with all the scientific WP to develop specific nanoparticles for arthritic pathologies with industrial requirements such as biocompatibility and upscalable methods to have enough quantity of materials for pharmacokinetic studies. We also studied in depth the biological behaviors of our nanohybrids (toxicity, internalization, biodistribution or Protein Corona).
