I graduated in 2023 from a double bachelor’s degree in Physics and Chemistry, at Université Paris Cité. Following this, I pursued a master’s degree in Chemistry, specializing in Chemistry for Energy and Nanosciences. During my studies, I learned various skills in nanoparticle synthesis and characterization. Thus in 2025, I joined the Matrix team at the LPS for my M2 internship where I am investigating the growth of colloidal crystals through microfluidic channels and studying the kinetics of their self-assembly. My internship is supervised by Dr. Cyrille Hamon, Dr. Marianne Impéror-Clerc and Jaime Gabriel Trazo. |

I started thinking about chemistry when I participated in international chemistry Olympiad, (ICHO) 48 where I became fascinated about science. Therefore, I studied chemistry at San Diego State University Georgia and obtained bachelor’s degree there. Then, I decided to divert study direction towards physical chemistry and materials science that is why I applied to SERP master program. Currently, I am involved in M2 internship in LPS where I work for the project “Templated Colloidal Crystals with Collective Optical or Magnetic Properties” which is supervised by Dr.Cyrille Hamon and Dr.Marianne Imperor-Clerc.
Currently, I am particularly interested in self-assembly of nanoparticles and how to utilize the properties of nanoparticles in the field of plasmonics/photonics and imaging. |

Marianne Impéror-Clerc

Marianne Impéror-Clerc has a permanent position at CNRS as ‘directrice de recherche’. She studied Physics at the ENS de Saint-Cloud (1986-1990) where she passed the ‘aggrégation de Physiques’ (1989) before obtaining her PhD (1992) and HdR ‘Habilitation à diriger des recherches’ (2007) at the Université Paris-Sud in Orsay. Her research is devoted to structural studies of self-assembled systems and her favorite experimental tool is Small Angle Scattering using X-rays or neutrons (SAXS and SANS). For example, for mesoporous materials, the control of the architecture of the porosity allows to optimize transport properties. Main goal is to control the nanostructure during the synthesis of such materials. For this, time-resolved scattering experiments allow to follow in real time the formation of the materials and to elucidate the mechanisms involved. Her research thus lies at the frontier between Soft Matter and Materials Chemistry. She is alos regularly involved in activities about Crystallography for education and the general public (http://www.cristallo2014.u-psud.fr/) |
