BiographyAfter an initial formation at the Chemistry Department of the Ecole Normale Supérieure (Paris), I collaborated with the Physics Department during my PhD, working on the development of magnetic tweezers and on the synthesis of oligonucleotide-made nanostructures. DNA biophysics was still at the heart of my two post-doctoral stays, at Keio University (Yokohama) and Institut Curie (Paris). Then, I entered the Laboratory for Photonics and Nanostructures (Marcoussis), shifting my activities towards microdevice fabrication and analytical sciences. Later, I also devised there several perturbative approaches to study the dynamics of reaction networks, at the molecular as well as at the cellular scale.
Back at the Ecole Normale Supérieure, in its Biology Department, my
research still focuses on the kinetics of biomolecules. I am conceiving
techniques to measure individual rate constants and exploiting the
obtained results to understand more complex reactive systems.
Fields of interest
Thermokinetics characterization of biomolecular interactions; comprehension of reactive network dynamics.
TechnologiesSingle-molecule micromanipulation; on chip microreactors; spectroscopy.
