Research

I am an associate Professor at Université Paris 13 where I develop my research interests on the optical and electrical properties of metallic nanoparticles. The production of hot electron by plasmon and their role in the enhancement of Raman scattering is in the centre of my interests. I apply these fundamental physics concept to the detection of emerging pollutants in water.

This year, I am a visitor in the group La physique autrement where, together with Julien Bobroff and Frédéric Bouquet, I will develop new supports for the diffusion of physics for a general audience.

My university training has started with undergraduate studies in material sciences at the University Pierre and Marie Curie in Paris (Now Sorbonne Université), I followed my interest in nanotechnologies by enrolling in a doctoral program at the Unité Mixte de Physique CNRS Thales where I developed my field of expertise in the growth and electrical properties of nanoparticles under the supervision of A. Friederich, F. Nguyen Van Dau and P. Seneor. After obtaining my Ph.D. in 2005, I joined the team of Prof. R. Palmer at the University of Birmingham where I studied the growth and deposition of size selected clusters and there interaction with proteins. The skills I developed in liquid phase AFM were valued through my second post-doc at the University of Evry under the supervision of S. Labdi and P. Curmi. In 2010 I was appointed as assistant Professor at the University of Paris 13 in the team of Prof. M. Lamy de la Chapelle. There, I have used and developed original lithographies techniques to fabricate large assembly of organized nanostructures for SERS (Surface Enhanced Raman Spectroscopy) based highly sensitive sensors. More specifically, I study the influence of molecule / nanoparticle interaction on the SERS signal.

Teaching

I also am an enthusiastic teacher. I have developed a focus group for higher education teachers where they can meet and discuss about issues in their teaching activities and the innovative answers they can bring.

I am testing some new concepts in my classroom such as the flipped classroom or the use of games in teaching.
