Project Description: Separation processes in industry account for 10 to 15% of global energy consumption and up to 60–80% of total costs. There is therefore a major incentive to develop energy-efficient and low-cost separation techniques. In this context, membrane filtrations techniques have become the state-of-the art tools for sustainable separations in aqueous media (water treatment, biotechnology, etc.). To date, these techniques are also emerging for applications in non-aqueous media, particularly in the fields of biorefineries, fine chemicals, and pharmaceuticals.
Fouling, i.e., the decline in separation performance during filtration, remains the main bottleneck of membrane technologies leading to increased energy consumption and reduced membrane lifespan. While fouling mechanisms have been widely studied in aqueous media, they remain largely unknown in non-aqueous environments. This PhD project therefore aims to investigate to what extent fouling mechanisms identified in aqueous media can be transposed (or not) to non-aqueous systems, thereby enabling the optimization of separations in these media.
Your work, primarily experimental, will be positioned at the interface between membrane process engineering and the physical chemistry of solutions and membrane materials. The research will be conducted in three interdependent phases: (1) studying membrane behavior in the selected media, (2) carrying out filtration experiments (microfiltration/ultrafiltration) using model foulants (particles, macromolecules), and (3) investigating fouling in a case representative of an industrial application (to be defined together during the PhD). To this end, you will rely on various characterization techniques for model foulants and membranes (dynamic light scattering, zeta potential, electron microscopy, etc.), combined with the analysis of global filtration parameters (permeability, hydraulic resistance, specific resistance, etc.).
You will be responsible for generating fundamental advances to improve understanding of the role of solvent/foulant/membrane interactions in fouling mechanisms in non-aqueous media.
Candidate profile: We are looking for candidates with a Master’s degree in chemical engineering, physical chemistry, or a related field.
You enjoy hands-on experimental work and are motivated by multidisciplinary topics and academic research. Experience with membrane processes is a plus. You are comfortable communicating in English in a scientific context (writing and presenting at international conferences).

Post-Doctoral Position at LGC Toulouse, France
We would like to announce a Post-Doc Position at LGC Toulouse (France) within the ANR PROJECT MIMEBIOTIC. The topic concerns the simulation of mass transfer and reaction kinetics in a hydrogel supported on membrane into an innovative bioreactor.
Duration: 18 months
Starting date: May-June 2026
Keywords: hydrogel, membrane, cell growth, transfer, simulation, millifluidics, intensification
Context: The MIMEBIOTIC project aims to propose an innovative and sustainable strategy for intensifying bioprocesses by developing a bioreactor based on a membrane-supported hydrogel. By immobilising cells in membrane-supported hydrogels (MSH), we can take advantage of a number of levers to increase productivity: cell densification, maintenance of optimal physiological conditions (particularly if the metabolite is inhibitory), compactness and ease of scaling up thanks to the use of hollow fibre membranes (by multiplying the modules) [1-3].
The Material and Membrane Process team at LGC (Toulouse, France) has developed a well-established expertise on membrane modification and membrane characterization. This team works in collaboration with an expert in mass transfer in millifluidic and microfluidic devices at the LGC and experts in microbiological and cell culture engineers in Toulouse Biotechnology Institute (TBI). In this project, we will focus on the design of a MSH to immobilize and densify microorganisms of interest for bioprocess intensification and use it to study transfers and kinetics for bioproduction purposes.
The aim of the present position is to simulate flows, mass transfers and microbial kinetics in a millifluidic device which hold the MSH.
The coupling between i) the flows (external and permeation through the hydrogel loaded with cells and the membrane), ii) the mass transfers of the species of interest (nutrient, O2, products formed, cell density,
...) and iii) the reaction kinetics of the microorganism (obtained by a TBI research engineer/or TBI team) within this model system will be modelled using Comsol Multiphysics software. The hydrogel and the membrane will be modelled as porous domains characterized by their effective transport (effective diffusion coefficients and permeabilities from first experiments) and microbial kinetics within hydrogel (obtained in TBI). The full coupling problem, involving relevant species (outside the cells such as substrate, O2, products formed, etc.), will be solved.
Complementary filtration experiments using a millifluidic device will be carried out to validate the models obtained from simulations, optimize the hydrodynamic operating conditions, and increase the production rate. These experiments will also make it possible to tune the properties of the MSH to meet the final objectives and to provide input for the development of a larger-scale model.
Profile:
Applicants are expected to hold a Ph.D. with expertise in simulation and/or experiments in the field of membrane science including mass transfer and reaction (bio)kinetics and scale up of processes, preferably in the case of bioprocesses. Additional experience in micro/millifluidics and microscopy would be a plus as well as having already used the Comsol software. The applicant should have the motivation and enthusiasm to lead the project from fundamental research to application. S/he should be able to work in a multidisciplinary team in collaboration with chemists, microbiologists and engineers in the lab or outside.
S/he will work in collaboration with another PhD student and a research engineer within the same project and will probably supervise undergraduate and/or graduate students. French spoken is a plus but not mandatory.
A selection of applicants will be invited to a face-to-face or a Teams interview with a panel of three professors; who will question her/his motivation, skills, enthusiasm and vision.
Application: Applications including a motivation letter, a comprehensive CV and the mail, address and phone number of two referees should be sent by March 20th, 2026 to Dr. Clémence Coetsier and Dr. Fabien Chauvet at the Laboratory of Chemical Engineering, LGC, UMR 5503, Toulouse University Department of Interfaces and Divided Media Engineering,

Research topic:
Enzymatic regeneration of NADH in the context of CO2 capture and conversion
The current emergency on climate change is accelerating the extreme need for technology can reduce CO2 emissions. Currently, CO2 capture and conversion is considered as the way to have economic advantage by using a 'waste' (CO2) to produce high value molecules. However, CO2 is a quite stable molecule and its conversion needs significant amount of energy, which could lead to more CO2 emissions depending on the energy source. This research is very challenging. Using enzymatic conversion in combination with membrane technology can truly reduce energy consumption and produce specific compounds with high purity. But here, two critical needs must be met:
- Enzymatic conversions require very expensive cofactors, such as NADH. Its regeneration is essential but not easy at low energy
- Commercial membranes are made of non-biosourced and potentially toxic polymers (e.g., PVDF) and using toxic solvents (e.g. NMP). A big concern has recently raised on the field of membrane technology due to the end of life of the membranes. They are plastics and they contribute to the current plastic
The PhD project will face those two challenges and proposes a new process and new membranes that are made with biosourced (and greener) polymers and solvents to be applied in the regeneration of NADH, required during enzymatic conversions of CO2 into high valuable products.
