Aram MELKONYAN, PhD student at the Hubert Curien lab, started to work on the QUICKSILICA Project.
Ultrafast electron-molecular dynamics coupling in photoexcited silica glass
Project leader: Elena KACHAN
The proposal consists in coupling molecular dynamics with advanced electromagnetic propagation and nonequilibrium collisional electrodynamics to describe the behavior of a silica glass excited by an ultrafast laser pulse. It aims to understand how laser excitations affect the complex topology of the amorphous network and lead to highly-localized changes of the physical properties.

Explainable deep models in cell imaging: application to the analysis of structural changes in human cells for diagnostic purpose
Project leader: Christophe DUCOTTET
The biological function of a cell is very often associated with its morphology. For example, in the case of human podocytes (cells involved in renal glomerular filtration), the morphological modifications observed on in vitro cultures are associated with a modification of the permeability and allow to quantify the toxicity level of a drug. This project proposes to jointly address first a problem of morphological characterization from biology and a computer vision problem based on advanced deep learning methods.
Anthony NAKHOUL is now working at the Georges Friedel lab on the HyTex project.
Influence of ultrafast laser texturing on hydrogen uptake and diffusion in metallic materials
Project leader: Alixe DRÉANO
When metallic materials are exposed to a hydrogen-rich environment, a decrease of their mechanical properties is observed. In order to mitigate such a phenomenon, one possibility is to reduce hydrogen uptake. However this implies a deeper comprehension of the interaction between hydrogen and the surface. In this project, it is proposed to explore the influence of the surface topography on hydrogen uptake.

Arthur GAUTHERON, postdoctoral fellow at the Hubert Curien lab, will be working on the BioSpec project.
Quantitative analysis of biomarkers by spectrometry
Project leader : Mathieu HÉBERT
Spectrophotometric analysis has many advantages for in vivo characterization of human biological tissues and classification of healthy or pathological tissues: it is fast and contactless. The search for spectral patterns allows for example to detect the presence of biological components, chromophores or fluorophores, characteristic of some tumors. The challenge of the project is to be able not only to detect but also to quantify these components, i.e. to estimate their concentration in a reliable way, in order for example to help the surgeon to decide the perimeter of the tumor area to be resected.

The MOTOM research project will start in March at the Hubert Curien lab, under the supervision of François ROYER.
Magnetic field steering Of the Thermo-chromic behavior Of Micro-structured surfaces
Project leade: François ROYER
The MOTOM project deals with the design, realization and study of microstructured surfaces exhibiting a magneto-chromic behavior: magnetic field steering of their ability to transmit or reflect light. The thermal power of magnetic nanoparticles (NPs) embedded in a composite material will be used to activate the thermo-chromic transition of vanadium dioxyde (VO2), through thermal transfert between both materials.
Ilemona Sunday OMEJE, PhD student at the Hubert Curien lab, is working on the EMIL project.
Numerical study of the wettability of hierarchical relief surfaces treated by femtosecond laser
Project leader: Tatiana ITINA
Femtosecond lasers are extremely versatile and promising for surface texturing since various structures can be produced ranging from laser-induced periodic surface structures (LIPSS) to much larger “grooves” and spikes. By varying laser parameters, such as laser pulse energy, temporal and spatial pulse shape, polarization, repetition rate and scanning rate, it is possible to create a wide range of surface reliefs, including complex reliefs, hierarchical structures, and biomimetic surfaces providing possibilities of an efficient control over not only optical properties, but, importantly, of surface wettability.
