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.
