A postdoctoral training position at the interface of Biophysics and 
Developmental Biology is available in the laboratory of Konstantin Doubrovinski, 
at UT Southwestern Medical Center, in collaboration with Dr. Weria Pezeshkian 
(University of Copenhagen). Our laboratory has been establishing unique 
measurement tools to probe cells and their constituents in developing embryos, 
with the aim of systematically mapping out material properties of cellular 
structures. The work focuses on uncovering the physical basis of tissue dynamics 
in the early fruit fly embryo. These data are indispensable for formulating 
comprehensive and predictive models of animal development. Recent experimental 
data have indicated that membranes and not actin cytoskeleton dominate 
mechanical properties of the cellular boundaries in the early fruit fly embryo. 
The aim of the project is twofold: (1) to model mechanical response 
(deformation) of embryonic tissue to external calibrated mechanical 
manipulations, and (2) to leverage the model of embryonic tissue mechanics for 
simulating the dynamics of tissue shape changes during the early fruit fly 
development.

On the theoretical side, the Pezeshkian lab has a unique expertise in simulating 
the dynamics of fluid membranes. On the experimental side, the Doubrovinski lab 
has established a comprehensive toolbox for directly measuring mechanical 
responses of embryonic tissue to well-calibrated external force. A combination 
of these tools has the unique potential to deliver a genuinely quantitative 
mechanical model of tissue dynamics driving embryonic development.

Candidates must hold a Ph.D. degree. Experience in computational physics is 
required. A background in biophysics/developmental biology is a plus.

Context and Objective
We focus on the development of passive and optimized filtration systems to address the growing environmental concern
of solid micropollutants, particularly microplastics, in industrial and urban water treatment networks. The project’s
core ambition is to design adaptive, modular filtering grids that can enhance pollutant separation while maintaining low
pressure loss and energy efficiency. These grids must be capable of inducing localized recirculations that promotes particle
trapping, without disrupting the overall flow dynamics. The research adopts an integrated approach that combines multi-
scale numerical modeling, advanced experimental fluid characterization, and data assimilation techniques to develop
and optimize these filtering systems. At the numerical level, the project builds on the MultiMatchGrid reduced-order
modeling framework carried out at Arts et Métiers, Lille. This tool couples computational fluid dynamics with machine
learning to simulate multiscale flow behaviors through complex geometries. The model will be continuously updated
and validated using experimental data from a large-scale test bench designed and operated at IMT Nord Europe, in
collaboration with SIAAP, France’s leading public wastewater utility. This test bench enables fine-grained measurements
using Lagrangian Particle Tracking Velocimetry (PTV), tailored to detect small-scale turbulent structures and particle
transport dynamics. To increase the robustness of the numerical model, the CONES library, developed at LMFL,
facilitates the integration of experimental data using data assimilation algorithms.
Planning (36 months)
The doctoral project is planned for three years, with a balanced effort between simulation development, experimental
campaigns, data assimilation, and system optimization. The candidate will engage in the:
1) Development of the reduced-order model and adaptation of MultiMatchGrid to grid geometries;
2) Experimental validation of the tool MultiMatchGrid by means of high-resolution metrology;
3) Coupling numerics/experiment by data assimilation and TRL enhancement.
Organization and Required Skills
The PhD will be jointly supervised by two highly complementary research teams: Arts et Métiers Lille, specialized in
multi-scale modeling, data assimilation and reduced-order simulation, and IMT Nord Europe, experienced in experimental
flow diagnostics and industrial fluid systems.
The research project will take place in part at Arts et Métiers - Institute of Technology (Campus of Lille) under the
scientific supervision of F. ROMANO and P. ERRANTE, and in part at IMT Nord Europe (Campus of Douai) under
the supervision of A. BAHRANI. This position is part of the ANR RéCLasSIF framework, a large-scale project focused
on proposing solutions for the industry of the future. The involvement of SIAAP ensures a strong ground in industrial
needs, with direct opportunities for transfer and implementation.
This position is intended either for a recently graduated or a Master’s student who will graduate before October 2025.
The candidate is expected to speak French and English, be experienced in Fluid Mechanics, Applied Mathematics,
or Thermal/Energy Engineering, with a strong interest in numerical modeling, simulation and data assimilation and
experimental fluid mechanics. Knowledge of a CFD code (such as OpenFOAM) and a programming language (such as
C++ and python) would be a plus.
