Short Bio:

I received a joint Engineering and Masters degree in Applied Mathematics and Computer Science from ENSEEIHT (National polytechnic institute of Toulouse) Toulouse, France and Chalmers University of Technology, Göteborg, Sweden. I then received a masters degree in High Performance Computing from the University of Edinburgh, Edinburgh, Scotland and a Phd in Computational Mechanics from Cardiff University, Cardiff, Wales for which I was awarded the Roger Owen  Best Phd Prize as well as being finalist of the ECCOMAS Phd Award. During my Phd, I was a visiting scholar for 9 months at Northwestern University, Evanston, IL, USA. I was then employed as a Postdoctoral Researcher by Inserm (National Institute of Health and Medical Research) to work on cochlear implant surgery simulation. In October 2016, I was recruited as a permanent researcher at Inria – Lille Nord Europe in the DEFROST team. In 2022, I moved to Inria Grenoble Alpes in the TRIPOP team to work on numerical methods for Natural risks in mountains.

Current Work:

I am currently working in the development of model order reduction methods for the fast and accurate simulation of soft-robots.  Indeed, Finite element (FEM) simulations are computationally very expensive and it is necessary to develop efficient numerical methods to be able to tackle the real-time constraint imposed for the accurate control of the soft robots.

I am also collaborating with Inserm on the accurate simulation of cochlear implant insertion. Cochlear implant surgery can be used for patients suffering from heavy hearing loss or even fully deaf. An electrode array is inserted into the tympanic ramp of the patient’s cochlea. The aim of the project is to develop a software able to accurately simulate the whole process of the implant insertion into the cochlea, with the idea of robotising the electrode array in the future.
