Are you passionate about advancing the science of soft materials and eager to contribute to innovative research with real-world applications in pharmaceuticals, cosmetics, and food products? If you are seeking to deepen your expertise in polymer physical chemistry while working at the forefront of compartmentalized aqueous systems, this fully funded PhD position at Sorbonne University in France could be the perfect opportunity to launch your research career.
About the University or Research Institute
Sorbonne University, based in the heart of Paris, is one of Europe’s most prestigious and historic institutions. Renowned for its rigorous academic standards and vibrant research culture, Sorbonne University brings together a diverse community of scholars from around the globe. The university is closely affiliated with the CNRS (French National Centre for Scientific Research), one of the world’s leading public research organizations.
The research for this PhD position will be conducted at the Soft Matter Science and Engineering Laboratory (SIMM), a joint research unit of CNRS at ESPCI Paris-PSL, and also under the umbrella of Sorbonne University. SIMM is internationally recognized for its pioneering work in the field of complex fluids and soft materials. The laboratory provides an exceptional environment for interdisciplinary research, equipped with state-of-the-art facilities for macromolecular synthesis, structural characterization, and advanced microscopy.
France itself is an attractive destination for international researchers, offering a high quality of life, rich cultural experiences, and a tradition of scientific excellence. Paris, as a global hub for innovation and academia, provides ample networking and collaboration opportunities, making it an ideal location for pursuing doctoral studies.
Research Topic and Significance
The central focus of this PhD project is the development and stabilization of water-in-water emulsions using complex coacervate core micelles. Water-in-water emulsions are ternary systems composed of water and two incompatible hydrophilic polymers. These systems hold significant promise for applications in the pharmaceutical, cosmetic, and food industries due to their potential for compartmentalization and biocompatibility.
However, the widespread adoption of water-in-water emulsions has been hampered by their inherent instability. The MUSCADET project aims to address this challenge by designing and synthesizing new classes of soft colloidal stabilizers—complex coacervate core micelles—engineered to adsorb at the water/water interface. By exploring the relationship between the chemical composition, morphology, and interfacial properties of these micelles, the research seeks to unlock new strategies for stabilizing emulsions, thus expanding their practical applications.
Understanding the mechanisms underlying the stabilization of these emulsions is not only scientifically significant but also has the potential to drive innovation in the formulation of compartmentalized products with enhanced performance and functionality.
Project Details
The successful candidate will join the MUSCADET project, which is dedicated to the multi-scale compartmentalization of aqueous systems. The project is supervised by Théo Merland, Assistant Professor at Sorbonne University, and Cécile Monteux, CNRS Research Director. The research will be based at the SIMM laboratory, benefiting from its expertise in soft matter and the extensive support network provided by CNRS and ESPCI Paris-PSL.
The PhD student will be responsible for:
– Formulating water-in-water emulsions and establishing phase diagrams.
– Preparing and thoroughly characterizing complex coacervate core micelles, both in bulk and at interfaces.
– Employing advanced structural characterization techniques such as scattering and cryo-transmission electron microscopy, in collaboration with a postdoctoral researcher specializing in copolymer synthesis.
– Investigating the link between the structural features of the co-assemblies—such as morphology, size, and core-to-shell ratio—and their ability to stabilize emulsions.
– Contributing to the development of bio-based co-assemblies by functionalizing polysaccharides and complexing them with proteins.
This work will provide fundamental insights into the behavior of soft colloids at interfaces and contribute to the broader understanding of dynamic stabilization mechanisms in complex fluids.
Candidate Profile
Applicants should possess a Master’s degree or engineering degree in chemistry, physical chemistry, or physics, with a focus on polymers, soft matter, or formulation science. Ideal candidates will have:
– Strong background in polymer science, soft matter, or colloidal systems.
– Experience in structural characterization methods (e.g., scattering techniques, microscopy), or in the formulation of dispersed systems.
– Analytical skills and a keen interest in interdisciplinary research.
– Motivation to work collaboratively in a dynamic, international research environment.
– A proactive approach to problem-solving and scientific inquiry.
This position is particularly well-suited for individuals aiming to build a career in academic or industrial research related to soft materials, complex fluids, or advanced formulation technologies.
