Graduated from a master's degree from the University of Orleans specialized in Mechatronics, Robotic Automation and Signal, I started my thesis in the Micro and Nanorobotics team of the AS2M department of Femto-St in October 2019.

My PhD work focuses on nanorobotics and miniature robotic origami, on the fabrication of nanosensors or active structures at the end of the optical fiber. The objective of this thesis is to develop and experimentally validate the tools of optical and robotic nanomanipulation to satisfy the needs of characterization systems and nanobots that operate at very small dimensional scales.

In my thesis, we propose a new approach, based on the deployment of a structure set up at the end of the fiber using robotic means under SEM. This involves pre-cutting a structure at the FIB level, configuring it, assembling it and generating its deployment at the end of the fiber and allowing its use using the available optical flow. The end or middle portions of the fiber end structure may be mirrors, coated or uncoated filters, monolayer reflectors, or multilayer filters at certain wavelengths of interest.

To support me in this doctorate, Philippe Lutz, Jean-Yves Rauch and Cédric Clévy will bring me the necessary help in the tripartite thesis that I begin to know: origami robotics, optics and micro-nanotechniques.
