I am an associate professor at the University Sorbonne Paris Nord. I have a background in materials science and I started working as a lecturer in 2010 in the department of Health and Medicine of my university, my laboratory (the CSPBAT) was very interdisciplinary. It brought together chemists, biochemists and physicists. In this environment, I developed research focused on the study of molecular plasmonics and its application to Surface Enhanced Raman Scattering (SERS). In September 2019, I joined the Laboratory of Sciences of Processes and Materials (LSPM) where materials scientists study matter and especially metals at the nanometric scale. I am now back in my favourite field: my university training is in materials science and my thesis work at the Unité Mixte de Physique CNRS Thales concerned the growth and study of the electronic properties of nanoparticles in tunnel effect junctions.
I like to take my research investigation from the design of the samples to their concrete applications, via the study of physical phenomena. My team and I work in nanofabrication to find new large-scale surface nanostructuring processes. We study the plasmonic properties of these nanostructures and we use the SERS effect in the context of collaborations with biologists or environmental specialists. For example, we have shown that it is possible to detect proteins in complex media such as blood or urine. Another application is the detection of pollutants in water, which involves other challenges such as the pre-concentration of contaminants.
The study of plasmonics has also led us to consider using the optical properties of gold nanoparticles to assist certain chemical reactions such as the thiol-ene reaction or the grafting of diazonium salts. This has notably enabled us to develop a method of regio-selective surface functionalisation.
I am also very involved in teaching. I teach at the University Sorbonne Paris Nord and I do most of my teaching at the IUT of Saint Denis (University Institute of Technology, where technical engineer are trained), within the département of material sciences and engineering. In this context, I like to try out new teaching methods such as games or the use of smartphones. I have also been in charge of projects at the Biological Engineering department of the Bobigny IUT, I invited students to work on the popularisation of their knowledge for primary schools children.
Popularising science is the last but not the least of my professional activities. I like to involve my students in this activity, which is how the project “Recruits of Science” was born. 400 children from underprivileged neighbourhoods were invited to take part in activities designed by the students.
Other projects are described in the “popularisation” section of this website, such as the project “Nano-factory”, in which the “why” and “how” of a clean room are explained. Also the project “Metamorphosis of materials”, which explains how a process is developed scientifically.
