Offer Description

Assignments :

With the help of the multidisciplinary research team at DEFROST/INRIA team, the recruited person will be taken to develop and validate a digital twin for the surgical insertion of an active cochlear implant, optimizing its design and enabling automated insertion techniques.

For a better knowledge of the proposed research subject :

Collaboration :
You will collaborate with a multidisciplinary team of researchers, biomedical engineers, and clinicians specializing in cochlear implant technology and surgical robotics. This role offers a unique opportunity to contribute to cutting-edge research with direct medical impact, including the potential to develop an operational prototype for preclinical testing. You will also have access to state-of-the-art facilities for simulation and experimental validation.

Responsibilities :

1. Code Integration with Simulation Platform:
- Adapt and integrate existing biomechanical modeling code into the SOFA master platform (or equivalent) for real-time simulation of cochlear implant insertion.
- Ensure compatibility with multiphysics simulation frameworks for fluid-structure and electromechanical interactions.

2. Modeling and Stabilization of Biomechanical Interactions:
- Develop and refine Cosserat-based models (or similar) to simulate the active deformation of the cochlear implant and its interactions with cochlear anatomy.
- Identify and resolve instabilities in the model, particularly during dynamic actuator control and contact with cochlear tissues.

3. Prototyping and Validation:
- Contribute to the design of a functional prototype of the active cochlear implant and its insertion system.
- Validate the digital twin through experimental tests in artificial cochlear models and cadaveric specimens, ensuring model accuracy and practical feasibility.

4. Optimization and Automation:
- Use the digital twin to optimize implant design (e.g., actuator placement, material properties) and insertion strategies.
- Develop control algorithms for real-time actuator adjustment, paving the way for automated insertion techniques.

Main activities :

1. Develop and refine biomechanical models (e.g., Cosserat-based) to simulate the active deformation of a cochlear implant and its interaction with cochlear anatomy.
2. Integrate and optimize simulation code into the SOFA platform for real-time modeling of implant insertion dynamics.
3. Identify and resolve algorithmic instabilities in the digital twin during actuator-driven deformations and tissue interactions.
4. Validate models and simulations through experimental tests using artificial cochlear models and cadaveric specimens.
5. Design and test control algorithms to optimize actuator performance and explore automated insertion techniques.

Additional Requirements for Postdoctoral Candidates:

• Scientific Communication: Proven ability to read, write, and present scientific papers in international journals and conferences.
• Bridging Theory and Practice:Skill in translating theoretical models into practical, clinically relevant solutions.
• Interdisciplinary Problem Solving: Ability to integrate knowledge from applied mathematics, biomechanics, and medical engineering.

Specific Requirements

Required Skills:

• Strong expertise in applied mathematics, particularly in modeling complex systems (e.g., Cosserat models, finite element methods, or multiphysics simulations).
• Advanced programming skills in C++ and/or Python, with experience in simulation frameworks (e.g., SOFA, COMSOL, ANSYS).
• Knowledge of biomechanical systems and medical applications, particularly in otology or soft robotics, is highly desirable.
• Problem-solving skills with the ability to propose innovative solutions to challenges in implant design and insertion.
• Familiarity with experimental validation techniques (e.g., force measurements, imaging-based verification).
