Dear Colleagues,

We have a postdoc opening in our fleXLab @ EPFL in the area of fluid-structure interaction at high Re, with a focus on experiments. The goal is to study the mechanisms underlying the coupling between fluid flow and multi-component morphing structures. Further details about this position, including a link to the online application system, can be found in the following link:
https://recruiting.epfl.ch/Vacancies/590/Description/2

Your mission: The Flexible Structures Laboratory (fleXLab) headed by Prof. Pedro Reis at EPFL invites applications for a postdoctoral research position in the area of fluid-structure interaction. The project will consist or exploring, understanding and designing morphable/flexible structures to achieve tunable lift and drag under high Reynolds number conditions, both in aerodynamic and hydrodynamic environments. The goal will be to both rationalize the fundamental principles that underlie the interaction between fluid flow and multi-component morphing structures, as well as then use the gained knowledge to explore implementation in engineering contexts. This activity will be multidisciplinary, at the interface of structural mechanics, fluid dynamics, soft robotics and nonlinear physics.

Your profile: Candidates should have recently obtained or are about to obtain a Ph.D. in Physics, or Mechanical/Civil/Aerospace Engineering, or related disciplines. The project will have a strong experimental component, so experience in laboratory settings is desired, either in fluid or solid mechanics. The following areas of expertise are particularly welcomed: rapid prototyping, micro-fabrication, polymer synthesis, mechanical testing, control/automation/robotics, flow imaging, and image processing. An appreciation for scaling analysis, theory and computation is also welcomed.

We offer: The successful postdoc will join a vibrant, international and diverse research team with interdisciplinary expertise in experimental, computational and theoretical mechanics. The focus of research activity at the fleXLab is centered around curiosity-driven research in the general area of physics and mechanics of soft/compliant mechanical structures. The fleXLab is hosted in the iconic modern building of the Institute of Mechanical Engineering and offers unique state-of-the-art laboratory facilities. More information about our research group, including other active research themes, can be found in the following link: https://flexlab.epfl.ch

Opportunities for involvement in the teaching of mechanics-related classes, both at the undergraduate and graduate levels, will be provided.

Applications received by August 20th, 2018, will receive equal consideration.

PROJECT:
A fundamental question in materials science is identifying the microscopic origin of plasticity. Why do materials display plastic rather than elastic response and can we predict when this will occur ? An improved understanding of plastic deformation is important in a wide range of amorphous materials, such as metallic and polymeric glasses, foams, granular materials, colloids, and emulsions.
In molecular materials with crystalline order, plastic behavior is understood in terms of defect nucleation and dynamics. For amorphous materials, a description in terms of topological defects is not possible due to the inherent structural disorder. Therefore identifying and characterizing local plastic events in amorphous materials is essential for a complete understanding of their structural and mechanical properties. Experimentally, the challenge is identifying systems for which the microscopic events are directly observable. This is one of the main advantages of mesoscopic systems, such as foams, and the reason for the interest in making connections between mesoscopic systems and molecular materials.
Foams are interesting as a model for atomic or molecular systems with tunable structural disorder (either quenched of evolving on large time scales) and interactions between units (from pairwise to many- body interactions). Foams are also a model for other soft cellular materials such as emulsions or confluent biological tissues: these systems are constituted of highly deformable (yet almost incompressible) units (bubbles, drops, cells,. . . ). Interfacial energy is the key ingredient in the cohesion and the rigidity of such systems, often constituted solely of fluids.
The proposal aims to bring a unified approach in the understanding of plastic behavior, for both molecular and cellular materials, with various degrees of disorder (from crystalline to amorphous). We will use in conjunction complementary numerical and theoretical models to study the plasticity of two-dimensional foams and compare it with the plasticity of atomic solids, either crystalline or amorphous.
SCIENTIFIC ENVIRONMENT:
The recruited post-doc will benefit from a world-class interdisciplinary environment, both within the MSC and LSPM labs which developed expertise in numerical and theoretical modelling of heterogeneous media.
SKILLS:
We seek motivated researchers, with theoretical and computational expertise. Candidates should have a background in computer simulation, statistical mechanics, or condensed matter. Postdoctoral position is for a period of one year, with estimated starting date January 2019.
CONTACT:
Interested candidates can apply by sending their CV (including publication list) and a short research statement (with plans and motivations) by email to marc.durand@univ-paris-diderot.fr with subject: « Application UNIPLAS ».

Postdoc fellowship in reactive fluid dynamics
Description

Within the MaSNEC project, the Nonlinear Physical Chemistry Unit (NLPC) of the Université libre de Bruxelles (ULB) invites applications for one Postdoc fellowship to begin in October 2018 or soon after.
MaSNEC (Material Synthesis in Non-Equilibrium Conditions) is a project funded by the European Union (EU) through the M-ERA.NET network. This network has been established to support and increase the coordination of European research and innovation programmes and related funding in materials science and engineering. This project involving 4 european partners is coordinated by NLPC.
General research performed at NLPC focuses on the experimental and theoretical study of spatio-temporal patterns and dynamics emerging from the coupling between chemical reactions and hydrodynamic flows. The research to be developed at NLPC in the context of the MaSNEC project aims to grow innovative materials and control their properties via synthesis in non-equilibrium reactive conditions maintained through convective flows due to injection of one reactant into the other. New experimental protocols are currently developed to take advantage of imposed out-of-equilibrium constraints to synthesize and control the growth of structured surfaces, composite coatings and multilayered tubes.
In this framework, we seek to hire a postdoc who will perform theoretical analyses in the context of flow-driven precipitation in porous media. The successful candidate will develop models based on continuum mechanics (fluid/solid mechanics, reaction-diffusion-convection dynamics) to rationalize experiments where the interplay between solid precipitate and hydrodynamic flows play a central role. He/She will develop models to understand how hydrodynamic flows affect precipitation reactions at the macroscale and to investigate how the amount and spatio-temporal distribution of precipitate depends on the experimental conditions.
Type of appointment

15 months full time. The successful candidate must have appropriate authorization to work in the EU before employment begins.
Salary

Approximately 2 400€ net per month.
Required Qualifications

PhD in Chemistry, Physics or related fields. Good oral and written communication skills (in English) to work in a multidisciplinary team environment. Good knowledge of reaction-diffusion(-convection) dynamics. Good knowledge of continuum mechanics (both fluid and solid).
Preferred Qualifications

Good programming skills to develop numerical codes complementing the theoretical analysis and to post-process and analyze experimental data through image analysis. Ability to write scientific publications and deliver scientific presentations in English.
